# Python does not have a do-while loop. You can however simulate
# it by using a while loop over True and breaking when a certain
# condition is met.
# Example:
i = 1
while True:
print(i)
i = i + 1
if(i > 3):
breakmyvariable = 10
while myvariable > 0:
print(myvariable)
myvariable -= 1There is no direct do while loop in python.# A python equivilant to do-while
n = 0
while True: # Do
print(n)
n += 1
if n%3 == 0: # While
break
# Output: 0, 1, 2# Program to add natural numbers up to 'n'
# sum = 1+2+3+...+n
n = 10
sum = 0
i = 1
while i <= n:
sum = sum + i
i = i+1 # update counter
# print the sum
print("The sum is", sum)
# To take input from the user,
# n = int(input("Enter n: "))# do while sample loop in python
# do statements in try while number is < 0
i = 0
number = -1
while number < 0:
try:
number = int(input("Enter a number: "))
print(number)
i += 1
except ValueError:
print("Invalid input")
