Python: SyntaxError: leading zeros in decimal integer literals are not permitted; use an 0o prefix for octal integers

Example:

integer_no = 0101

print(integer_no)

Error:

SyntaxError: leading zeros in decimal integer literals are not permitted; 

use an 0o prefix for octal integers

Reason for leading zero SyntaxError

In Python Programming, leading zeroes to a number value is not allowed, as having a leading zero, the number (assumed to be decimal - base 10) is considered to be an Oactal number (to the base 8)

But even to represent a number of octal (base 8( type, you have to add prefix 0o (Numeric 0 followed by lowercase letter o)

Solution/Fix

There could be one of these solutions based on what you are trying to achieve.

1. If the number is a decimal number

Simply remove the zero prefixed to the number.

Example:

decimal_no = 101




2. If the number is an octal number

Add a lowercase letter 0o before the number.

Example:

octal_no = 0o101




3. If the value is to be a String

Surround the number with either a single or double quote.

Example:

string = "0101"
