Python and percentages -

is there proper way handle percentages in python?

for example, how handle value 0.01 , make displayed 1%

you can use str.format()

percentage = 0.01 print "{0:.0f}%".format(percentage * 100) 

1%

percentage = 0.0142 print "{0:.0f}%".format(percentage * 100) 

1%

percentage = 0.0142 print "{0:.1f}%".format(percentage * 100) 

1.4%
