Python Programming Tutorial - 16: Nested IF-ELSE Statement

In this tutorial we'll check out an interesting application of the nested if-else statement using a programming example.

[mamc]

I just don't get the purpose of the elif statement in this code. Why not just have it as an if as well, it seems to work the same?

[nelsonkane]

I can't get this to work. But there is no way to contact "The Bad Tutorials, " I've noticed, if we have questions. Is there any way to contact The Bad Tutorials?

i am running this code in linux terminal. first i have made nested.py file and then running it on linux terminal. and when i enter somthing it shows me error:

Traceback (most recent call last):
  File "nested_if.py", line 4, in <module>
    if ord(char)>=65 and ord(char)<=90:           #A=65 Z=90 z=122
TypeError: ord() expected string of length 1, but int found

I liked the ELIF tutorial but instead of initializing a variable you can go with getting the input from the user i think that would be much useful for the programmers .

[arjit]

awesome sir, i studied python, sql and c from your tutorials.please make videos on data structure also ....:)

[pinkeishz]

I'm getting error in line 5, 7, 11 and 13 depends upon value, can anyone guide me?

[divayanshudeo]

I running this code but it give error

Traceback (most recent call last):
  File "C:/Python27/word.py", line 1, in <module>
    char=input()
  File "<string>", line 1, in <module>
NameError: name 'R' is not defined
 how to fix it?

[gouthamkumar]

why you have used elif in between when you can just continue using else and if statements

[UdayKumar-hedq]

I did get one issue like this

please enter numbera
Traceback (most recent call last):
File "C:/Users/Uday and else.py", line 2, in <module>
if ord (alphabett)>=65 and (alphabett)<=90 :
TypeError: '<=' not supported between instances of 'str' and 'int'
>>>
anybody can tell me about that issue.

Thank you very, very much Madhur.
Your presentation is excellent.
Minor typo (hardly worth mentioning), "entered" not "enetered"

[shihabkhan]

Nice videos.

English language has a single alphabet with 26 letters.

I just didn't get one thing which i have seen in other programming languages why do we have to restart the shell every time to check the condition

[AshishSk-askAshish]

check out the following codes where you are free to work with any numbers, instead of initialization :


print(" This Coding has been done by Ashish Sreekumar :\n")
print(" Check whether you earned a profit or loss or maybe niether of it  :\n")
print(" Enter the cost price of the item :")
cp = float(input () )
print (" Enter the selling price of the item  :")
sp = float(input ())

if (sp>cp):
     print ("Congratulations ! ")
     print ("You earned a profit of :", sp-cp, "Euros")
elif (cp>sp):
     print(" oops !")
     print("You made a loss of : ", cp-sp, "Euros")
else:
     print("You sold the commodity at it's actual cost price of :", sp, "Euros")
     print("So you niether earn a profit nor a loss :")
print("Thanks for using Python Ashish Sreekumar  :")

[gokulneov]

var1="Gopal"
var2="Gokul"
var3="Chinju"
var4="Mary"

char=input()
if char is var1:
print("He is the father")
elif char is var2:
print("This is me!!")
elif char is var3:
print("This is my sister!!")
elif char is var4:
print("This is mom!!")
else:
print("They are outsiders")


What is the error in this code? No matter what i give as input, i get only "They are outsiders" as output
