这样修改后,代码就不会再抛出“SyntaxError: leading zeros in decimal integer literals are not permitted”的错误了。
Python List: SyntaxError: leading zeros in decimal integer literals are not permitted 在Python中,列表是一种非常常见和有用的数据结构。它可以用于存储和操作一组数据。然而,在使用列表时,有时会出现SyntaxError: leading zeros in decimal integer literals are not permitted的错误。本文将介绍这个错误的原因以及...
The bin function converts an integer number to a binary string prefixed with "0b". The result is a valid Python expression that could be evaluated back to the original number. Key characteristics: accepts integers (positive or negative), returns a string, and always includes the "0b" ...
