Python f-string format also allows you to display an integer in different bases. The f-strings have the f
prefix and use {}
brackets to evaluate values.
Python f-string format integer
Simple example code.
age = 100
print('%d years old' % (age))
print('{} years old'.format(age))
print(f'{age} years old')
Output:

Python f-string integer with thousands of commas and space padded, the number is the width of the field. By default, they are right aligned.
a = 123456789
b = 12345678
print(f"{a:12,d}\n{b:12,d}")
Output:
123,456,789
12,345,678
Floating point values have the f
suffix. We can also specify the precision: the number of decimal places. The precision is a value that goes right after the dot character.
val = 10.3
print(f'{val:.2f}')
print(f'{val:.5f}')
Output:
10.30
10.30000
