How to print a percentage value in python?

How do I print a percent?

printf("%%"); Or you could use ASCII code and write: printf("%c", 37);

How do you use %s in Python?

The %s operator is put where the string is to be specified. The number of values you want to append to a string should be equivalent to the number specified in parentheses after the % operator at the end of the string value. The following Python code illustrates the way of performing string formatting.

What is %s %d %F in Python?

Answer. In Python, string formatters are essentially placeholders that let us pass in different values into some formatted string. The %d formatter is used to input decimal values, or whole numbers. If you provide a float value, it will convert it to a whole number, by truncating the values after the decimal point.


format supports a percentage floating point precision type:

>>> print "{0:.0%}".format(1./3)
33%

If you don't want integer division, you can import Python3's division from __future__:

>>> from __future__ import division
>>> 1 / 3
0.3333333333333333

# The above 33% example would could now be written without the explicit
# float conversion:
>>> print "{0:.0f}%".format(1/3 * 100)
33%

# Or even shorter using the format mini language:
>>> print "{:.0%}".format(1/3)
33%

There is a way more convenient 'percent'-formatting option for the .format() format method:

>>> '{:.1%}'.format(1/3.0)
'33.3%'

Just for the sake of completeness, since I noticed no one suggested this simple approach:

>>> print("%.0f%%" % (100 * 1.0/3))
33%

Details:

  • %.0f stands for "print a float with 0 decimal places", so %.2f would print 33.33
  • %% prints a literal %. A bit cleaner than your original +'%'
  • 1.0 instead of 1 takes care of coercing the division to float, so no more 0.0

Just to add Python 3 f-string solution

prob = 1.0/3.0
print(f"{prob:.0%}")
