How to format numbers to strings in Python?

You can format a floating number to a fixed width in Python using the format function on the string. 

example

nums = [0.555555555555, 1, 12.0542184, 5589.6654753]
for x in nums:
   print("{:10.4f}".format(x))

Output

This will give the output −

0.5556
1.0000
12.0542
5589.6655

Example

Using the same function, you can also format integers −

nums = [5, 20, 500]
for x in nums:
   print("{:d}".format(x))

Output

This will give the output −

5
20
500

Example

You can use it to provide padding as well, by specifying the number before d:

nums = [5, 20, 500]
for x in nums:
   print("{:4d}".format(x))

Output

This will give the output −

5
20
500
