Do-While loop in Python
In Python, there is no native do-while
loop construct. However, you can achieve similar functionality using a while True
loop and a conditional break
statement to exit the loop when the desired condition is met.
# Initialize a variable
count = 0
# Execute the loop body at least once
while True:
print(count) # Print the current value of count
count += 1 # Increment count by 1
if count >= 5:
break # Exit loop if count is equal to or greater than 5
Output
0 1 2 3 4
Explanation: In Python, we initiate a while True
loop, ensuring that the loop body executes at least once. Inside the loop, we print the current value of count
and then increment it by 1
. The loop continues until the condition count >= 5
becomes True
, at which point we use a break
statement to exit the loop.
Do-While loop in Programming
Do-while loop is a control flow statement found in many programming languages. It is similar to the while loop, but with one key difference: the condition is evaluated after the execution of the loop’s body, ensuring that the loop’s body is executed at least once. In this article, we will learn about the basics of Do while loop, its syntax and its usage in different languages.
