[Python Programming Basics to Advanced] : Nested if-else statement | Lab 06 P-1

This Python programming playlist is designed to take beginners with zero programming experience to an expert level. The course covers installation, basic syntax, practical scenarios, and efficient logic building. The course material includes PDF handouts, review questions, and covers a wide range of topics, from data types to advanced functions like Lambda and Recursive functions, Generators, and JSON data parsing.

In last lesson we studied about if and if-else statements. In this lesson we will study about Nested if-else statement in Python. Nested if-else means an if statement inside another if or else statement.

Review Questions:
1- Here is another version of the insurance problem:
s=input('Are you married? (m/u):')
g=input('Your gender? (m/f):')
a=int(input('Your age? :'))
if(s=='m'):
print('Eligible')
else:
if(g=='m' and a＞30):
print('Eligible')
else:
print('Not Eligible')
if(g=='f' and a ＞25):
print('Eligible')
else:
print('Not Eligible')
When I gave these inputs: unmarried, male and 27, the output was "Not Eligible" but printed twice.
Use the debugging tool and identify the reason for 2-times display.

2- Write a program that asks the user to enter his or her month and day of birth (as in the last task discussed in video). Then your program should print the user’s zodiac sign as part of an appropriate output message. The detail of zodiac sign is as under:

Capricorn December 22 to January 19
Aquarius January 20 to February 18
Pisces February 19 to March 20
Aries March 21 to April 19
Taurus April 20 to May 20
Gemini May 21 to June 20
Cancer June 21 to July 22
Leo July 23 to August 22
Virgo August 23 to September 22
Libra September 23 to October 22
Scorpio October 23 to November 21
Sagittarius November 22 to December 21

In the first question, in the first else block, there are two independent if blocks, they will both be executed no matter what the inputs are.

m=eval(input('Enter month number: '))
d=eval(input('Enter Day: '))
if (m==1):
if (d<=19):

Q1:
The reason for twice result is that there are two independent IF conditions, to display the output once, the correct one is as follow:
s=input("are you mariiied [m/u]: ")
g=input("write your gender[m/f]: ")
a=int(input("write your age: "))
if(s=="m"):
print("eligible")
else:
if(g=="m" and a>30):
print("eligible")
if(g=="f" and a>25):
print("eligible")
else:
print("not eligible")
Q2:
m=eval(input("enter a month: "))
d=eval(input("enter a day: "))
if(m==1):
if(d<=19):
x="capricon"
else:
x="aquarius"
if(m==2):
if(d<=18):
x="aquarius"

[abdulrehmankhalid]

Task1:
In else block there are two independent else statements and both executed at same time, that's why "Not Eligible'" printed twice. correct one is given:
s=input('Are you married:m/u')
g=input('Enter gender m/f:')
a=int(input('Enter your age:'))
if(s=='m'):
print('Elligible')
else:
if(g=='m'and a>30):
print('Elligible')
else:
if(g=='f'and a>25):
print('Elligible')
else:
print('Not elligible')

Task2:
m=input('Enter your birth month:')
d=eval(input('Enter your date of birth:'))

if(m=='january'):
if(d<=19):

[muhammadalihaider]

1)
This is because the "if(g=='m' and a＞30):
" and "if(g=='f' and a ＞25):" statements are two independent statements. If the (s=='m') condition in the first If statement is false, then the interpreter jumps to the else block, and reads the two if-else statements individually and executes the statements inside according to the validity of the conditions. In the given case (unmarried, male and 27), conditions in both the if statements are false, ultimately, the interpreter executes the print statements in both the else blocks separately hence the two 'Not eligible' outputs.

The correct program will be,

s=input('Are you married? (m/u):')

g=input('Your gender? (m/f):')
a=int(input('Your age? :'))
if(s=='m'):
print('Eligible')
else:
if(g=='m' and a>30):
print('Eligible')
else:
if(g=='f' and a >25):
print('Eligible')
else:
print('Not Eligible')

d=eval(input('\nEnter your date of birth (1-31):\t'))
m=eval(input('Enter your month of birth (1-12):\t'))

or (d>29 and m==2)):
print('\ninvalid date\n')

Q1:
The reason for displaying output 2 times is that there are two else conditions at the last of the code that are independent and display the output independently. If both the IF conditions are not satisfied after first else condition then it displays "Not Eligible" two times because of two independent else conditions. So, there is no need of second last else condition of "Not Eligible".
The correct one is as under:
s=input('Are you married? (m/u):')
g=input('Your gender? (m/f):')

[ahmedimran]

Answer 1:
The the reason for twice times the "Not Eligible " statement is because the last four if:else and if:else conditions have the same indentation. The last if :else condition must have separate indentation.

Answer2:
x = eval(input('Month : '))
y = eval(input('Day: '))
if (x==1 and 1<=y<=19) or (x==12 and 22<=y<=31) :
print('Capricon')
elif x==1 and 20<=y<=31 or (x==2 and 1<=y<=18):
print('Aquarius')
elif(x==2 and 19<=y<=29) or (x==3 and 1<=y<=20):
print('Pisces')
elif(x==3 and 21<=y<=31)or (x==4 and 1<=y<=19):
print('Aries')
elif(x==4 and 20<=y<=30) or (x==5 and 1<=y<=20):
print('Taurus')
elif(x==5 and 21<=y<=31) or (x==6 and 1<=y<=20):

Q:1
Given the code for Q#1 will give "Not Eligible" two times because the last two "if" conditions are independent and they will print their results separately. So we will re write in such a way that last condition will be executed only if second last is false.
The following program is the corrected one:
s=input('Are you married? (m/u):')
g=input('Your gender? (m/f):')
a=int(input('Your age? :'))
if(s=='m'):

Question--1
there are two else conditions which display their output if (if) condition is not met, in first case 'not eligible' is displayed as age is not met and in second else is triggered due to gender.
this issue can be resolved by removing 2nd last else statement.

The Reason for getting is twice is that the last 2 if statements are independent there is an unnecessary print statement. By removing the unnecessary statement and indenting the last if-else the program can be corrected. The correct one will be



a=int(input('Your age? :'))
if(s=='m'):
    print('Eligible')
else:
    if(g=='m' and a>30):
        print('Eligible')

Question 1:
The reason of problem of getting "NOT ELIGIBLE" twice is that there are two print statements of "NOT ELIGIBLE". By removing the unnecessary print statement, we can have our answer correctly as follows
s=input('Are you married? (m/u):')
g=input('Your gender? (m/f):')
a=int(input('Your age? :'))
if(s=='m'):
print('Eligible')
else:
if(g=='m' and a>30):
print('Eligible')

if(g=='f' and a>25):
print('Eligible')
else:
print('Not Eligible')
Question 2
m=eval(input("Enter month: "))
d=eval(input("enter day: "))

if m==1:
if(d<=19):

if(d<=18):

Q1):
The reason for displaying output two times is that last two else conditions are independent and display output independently. If both the (if) conditions are not satisfied after first else condition then it displays "Not Eligible" two times because of two independent else conditions. So, there is no need of second last else condition of "Not Eligible". The following program is the corrected one:

s=input('Are you married? (m/u): ')
g=input('Your gender? (m/f): ')
a=int(input('Your age?: '))
if(s=='m'):
print('Eligible')
else:
if(g=='m' and a>30):
print('Eligible')
if(g=='f' and a>25):
print('Eligible')
else:
print('Not Eligible')
​Q2​):
m=input('Enter your month of birth (lower case): ')
d=int(input('Enter your date of birth: '))
if(m=='december'):
if(d<=21):
a='Sagittarius'

if(d<=19):

else:

if(d<=18):

Task#1
The program is showing two times 'Not Eligible' because we have used two independent if statements and if any of two statement is false the program would print 'Not Eligible' and if both are false the program would print it two time. So to overcome this error will use single a dependent if statement as mentioned below:


a=int(input('Your age? :'))
if(s=='m'):
    print('Eligible')
else:
    if(g=='m' and a>30):
        print('Eligible')
    else:
        if(g=='f' and a>25):
            print('Eligible')
        else:

Q#1:The reason of getting Two times 'Not Eligible' is the two independent if-else statements in the else block and they give output independently. As if the both 'if' statements are not satisfied, in the else block, then it will display the output 'Not Eligible ' two times, so there is need of writing the second last else statement in the else block, the correct code is:

g=input('Your gender? (m/f):')
a=int(input('Your age? :'))

Assalam-o-Alaikum sir,
Task no 1:
We are getting 'Not Eligible' statement two times because the last two if-else conditions are displaying their result seperately.We can correct it by removing the print("Not Eligible")using after second if condition.
so the following code is given below:
s=input('Are you married? (m/u):')
g=input('Your gender? (m/f):')
a=int(input('Your age? :'))
if(s=='m'):
print('Eligible')
else:
if(g=='m' and a>30):
print('Eligible')
else:
if(g=='f' and a>25):
print('Eligible')
else:
print('Not Eligible')
