Folder or truncated string based on fixed length

There is currently code that looks something like this:

print '{: <5}'.format('test')

This will contain my string c ' '

if it is less than 5 characters. If the string is more than 5 characters long, I need the string to be truncated.

Without explicitly checking the length of my string before formatting it, is there a better way to shim if it's less than a fixed length, or truncated if it's greater than a fixed length?

You can use 5.5

to combine truncation and padding so that the output is always five in length:



'{:5.5}'.format('testsdf')
# 'tests'

'{:5.5}'.format('test')
# 'test '
+6

You can use str.ljust

and cut the line:



>>> 'testsdf'.ljust(5)[:5]
'tests'
>>> 'test'.ljust(5)[:5]
'test '
+1
