How to Use %d in Python

The following code illustrates the usage of %d.

frac_num = 8/3
print("Rational number formatting using %d")
print("%d is equal to 8/3 using this operator." % frac_num)
dec_num = 10.9785
print("Decimal number formatting using %d")

print("%d is equal to 10.9785 using this operator." % dec_num)

Difference Between %s and %d?

It is used as a backup for string values. It is used to get rid of numeric values.Uses string conversion via str() before straining. Uses decimal conversion via intrapunturing before strangling.%s can accept numeric values also and it automatically does the type conversion. In case a string is specified for the %d operator, a type error is returned.
