while loop in python is used to make a declaration block repeatedly until the given condition is true. And if the condition declines, line up immediately after the loop is removed from the system. While the loop falls under the category of endless repetition. Unlimited multiplication means that the number of times the loop is used is not clearly specified in advance.
Syntax of While loops
Statements represent all statements that have been postponed for the same number of character spaces after the program structure was considered as part of a single block of code. Python uses indentation as its method of compiling statements. When a temporary loop is used, the condition is first tested in the Boolean context and if true, the loop body is used. Then the condition is checked again, if it is still true then the body is killed again and this continues until the statement becomes a lie.
Example of while loop in python
count = 0
while (count < 3):
count = count + 1
print("Simitech")Output
Simitech Simitech Simitech
while loop in python with else
As discussed above, while the loop uses the block until the situation is satisfying. If the condition is false, the statement immediately after the loop is released. “else” clause is only used when your status is false. If you get out of the loop, or if something different is raised, it will not be done.
So, the else statement is there to use anything while the program dissatisfies the loop the else is executed in the program.
Note: The else is only executed when the break statement is not present. Let us understand in the example:
j = 0
while j < 6:
j += 1
print(j)
else:
print("No Break")Output
1 2 3 4 No Break
With break statement.
The break statement is there to forcefully exit the loop and stop the repetition.
j = 0
while j < 6:
j += 1
print(j)
break
else:
print("No Break")Output
1 2 3 4
Also, in the “While” loop, you can use all the loop control statements.
