How to print +1 in Python, as +1 (with plus sign) instead of 1?

With the % operator:

print '%+d' % score

With str.format:

print '{0:+d}'.format(score)

You can see the documentation for the formatting mini-language here.

score = 0.2724
print(f'{score:+g}') # or use +f to desired decimal places
# prints -> +0.2724

percentage

score = 0.272425
print(f'{score:+.2%}')
# prints -> +27.24%
