Learn Python — Iteration (for loop, while loop)

In my previous post variables and conditional statement covered.

Now let’s see Iteration (for loop, while loop)

So many ways I can use for loop

I can iterate through string like this

for character in “Nikhil”:
print character

Output:

N
i
k
h
i
l

Also, I can iterate through an array

numbers = [1,2,3,4,5,6,7,8,9,0]
for number in numbers:
print number

Output:

1
2
3
4
5
6
7
8
9
0

Now suppose I want to iterate between range from 4 to 11, then in python its very easy

for number in range(4,11):
print number

Output:

4
5
6
7
8
9
10
11

Hmm.. this is really cool. Let’s look at while

number = 4
while number <=11:
print number
number += 1

Output:

4
5
6
7
8
9
10
11

I am trying while with boolean. Yes its simple and expected

student_passed = true
while student_passed:
print(“Congratulations!!!”)

Output:

Congratulations!!!
