Expand Post »

Hi all, I have found some examples on the net but was not able to use the technique..

here is what I would like to do.

tst = 2
numOfDigits = 3
# change this to
tst2 = 002

Any help is appreciated.
Thank you.

Re: 1 digit number 2 to 3 digit number 002

You can use one of the built-in string functions ...

Python Syntax (Toggle Plain Text)
n = 2
digits = 3
ns = str(n).rjust(digits, '0')
 
print(ns)  # 002
n = 2
digits = 3
ns = str(n).rjust(digits, '0')

print(ns)  # 002

You can also use format

python Syntax (Toggle Plain Text)
message = "z's value is {z:0{digits}n}".format(z=2, digits=3)
print(message)
message = "z's value is {z:0{digits}n}".format(z=2, digits=3)
print(message)

Thank you vegaseat and gribouillis. That's exactly what I wanted to know. I'm using vegaseat's method for now.

Cheers.

Re: 1 digit number 2 to 3 digit number 002

There is an even more specific string function ....

python Syntax (Toggle Plain Text)
n = 2
digits = 3
ns = str(n).zfill(digits)
 
print(ns)  # 002
n = 2
digits = 3
ns = str(n).zfill(digits)

print(ns)  # 002

These string functions work with Python2 and Python3.

Gribouillis, thanks for the Python3 code.
