Python tutorial for Beginners [Full Course] Understanding Loops and constructs in Python. Part 10

This python tutorial covers important aspects of programming with python modules like For loop and foreach loop for logic building and effective problem solving using Python Loops and condition based loops in python apart from learning basic fundamentals of python in tutorial also covers broader topics like using range() and round() function inside or outside the for loop, static and dynamic loop conditions in python. this python tutorial also covers following list of topics.

Today's training session on Python includes
1. Understanding for-each loop in python
2. Using nested for loops in python
2. Working with condition based loops in python
3. Working with nested conditions inside loops in python
4. Understanding round() and range() function in python
5. Drawing different patterns using loops in python
6. printing ODD and EVEN numbers using loops in python
7. Using static and dynamic conditions with for and while loop

num=1
while num<=100:
num=num+1
for i in range(2, num):
if num%i ==0:
print(num, "...not prime")
break
else:
print(num, "...is a prime")

[muzaffarlone]

for num in range(1, 101):
if num > 1: #bcoz prime numbers are greater than 1
for i in range(2, num):
if (num % i) == 0:
break
else:
print(num)

def checkPrime(num):
if num == 1:
return False
for i in range(2, num):
if num % i == 0:
return False
return True

if (j % b) == 0:
break

print(j, "is a prime number")

[zamirmir]

for i in range (2, 101):
for j in range (2, i):
if (i % j)==0:
break
else:
print (i)

[shafqattahmad]

for num in range(1, 101):

for i in range(2, (num-1)):
if(num%i==0):
count=count+1
break
if(count==0 and num!=1):

[xubayrahmad]

for x in range (1, 101):
if x>1:
for y in range(2, x) :
if (x%y)==0:
break
else:
print(x, "is prime")

[muminfarooq]

Being more pythonic we can check prime nos by:
For num in range(2, 100):
If all(x%num!=0 for x in range(2, int(math.sqrt(num))+1)):
Print(no)..
One line code😊

print("Prime numbers in range 1 to 100 are:")


for i in range(1, 101):
for j in range(2, i):
if i%j ==0:
break
else:
print(i, end=" ")

Sir I have tried this program:
#Program to print the prime numbers


n=int(input("Enter the range upto which you want to print the numbers ="))
for i in range(2, n):
for j in range(2, i+1):
if i==j:
print("{} is a prime number".format(i))
break
if i%j==0:
print("{} is not a prime number".format(i))
break
else:
print("{} is a prime number".format(i))
break

> program to print the prime numbers from 1 -100 :
PROGRAM:
print(" prime nos from 1 - 100 are : ")
for i in range (1, 101):
count=0
for j in range (1, 101):
if i%j==0:
count=count+1
if count==2:
print (i)

OUTPUT:
prime nos from 1 - 100 are :
2
3
5
7
11
13
17
