python while

1# Python does not have a do-while loop. You can however simulate
2# it by using a while loop over True and breaking when a certain
3# condition is met.
4# Example:
5i = 1
6while True:
7    print(i)
8    i = i + 1
9    if(i > 3):
10        break

1myvariable = 10
2while myvariable > 0:
3  print(myvariable)
4  myvariable -= 1

1# A while loop is basically a "if" statement that will repeat itself
2# It will continue iterating over itself untill the condition is False

7while python_is_cool:
8	if first_time:
9		print("python is cool!")
10    else:
11      first_time = False
12      
13print("Done")
14
15# The while loop can be terminated with a "break" statement.
16# In such cases, the "else" part is ignored. 
17# Hence, a while loop's "else" part runs if no break occurs and the condition is False.
18# Example to illustrate the use of else statement with the while loop:
19  
20counter = 0
21
22while counter < 3:
23    print("Inside loop")
24    counter = counter + 1
25else:
26    print("Inside else")

1while (condition):
2  doThis();

1j = 0
2while j < 3:
3  print("hello") # Or whatever you want
4  j += 1
5#This runs the loop until reaches 3 and above

1# a while loop repeats its instructions as long as the condition is met
2# this one will loop indefinitely

8# while loops are useful when you don't know the number 
9# of times you want to iterate in advance
