Digit count program in python-CodePudding

This is a program which counts the no. of digits a user input in the programm.

n=int(input("Your no. :"))
dcount=0 
while n>0:
     dcount=dcount 1
print(dcount)

I make a while loop , was expecting the result but insted of counting the digits of the user input no. ,the output is showing nothing.

CodePudding user response：

If you want to count amount of digits in presented integer, you should divide n until n > 0, so your condition will work.

n = int(input("Your no. :"))
amount = 0 
while n > 0:
    n //= 10
    amount  = 1
print(amount)

CodePudding user response：

because the code was incomplete. print will only work when loop stop. in your code the loop will never stop, because the n value didn't come to zero. so you add n//= 10 inside loop. it will work. and you tell me what this n//= 10 do.

need to break the cycle somewhere
