How to right-align a column of numbers?

I have the following python code :

#This program converts the speeds 60 KPH
#through 130 KPH (in 10 kph increments)
#to MPH

#Global constants
START = 60
END = 131
INCREMENT = 10
CONVERSION_FACTOR = 0.6214

def main():
    #Print the table headings
    print('KPH\t\tMPH')
    print('----------------')

    #Print the speeds
    for kph in range(START, END, INCREMENT):
        mph = kph * CONVERSION_FACTOR
        print(kph, '\t\t', format(mph, '.1f'))

#Call the main function
main()

Running this code I get the following result :

KPH     MPH
----------------
60       37.3
70       43.5
80       49.7
90       55.9
100          62.1
110          68.4
120          74.6
130          80.8

How can I right align the second column, so that my results are shown more properly?

Use the Format Specification Mini-Language

"{:>10.3}".format(12.34)

Result (using _ for spaces ):

______12.3

You could use printf style formating to specify width too.

>>> print('%10.2f' % 1.23456)
      1.12

In your example you could use:

print('%-10i%.1f' % (kph, mph))
