Add leading Zero Python
python, string
Solution
You can use the builtin `str.zfill` method, like this
my_string = "1"
print my_string.zfill(2) # Prints 01
my_string = "1000"
print my_string.zfill(2) # Prints 1000
From the docs,
Return the numeric string left filled with zeros in a string of length width. A sign prefix is handled correctly. The original string is returned if width is less than or equal to len(s).
So, if the actual string's length is more than the width specified (parameter passed to `zfill`) the string is returned as it is.
Problem
I was wondering if someone could help me add a leading zero to this existing string when the digits are sings (eg 1-9). Here is the string: ``` str(int(length)/1440/60) ```
