SyntaxError: invalid character in identifier是啥

SyntaxError: invalid character in identifier是一种Python语法错误，意思是标识符中有一个无效字符。在Python中，标识符是用于标识变量、函数、类等名称的字符串。标识符必须以字母或下划线开头，并且只能包含字母、数字和下划线。如果标识符包含其他字符，例如空格、符号或中文字符，Python会抛出SyntaxError: invalid character in identifier错误。

SyntaxError: invalid character in identifier

This error occurs when an identifier (such as a variable, function or class name) contains an invalid character.

An identifier in Python must start with a letter or underscore, and can only contain letters, underscores, and digits. It cannot contain spaces or special characters like @, #, $, %, etc.

For example, if you try to define a variable with a name that contains a space:

my variable = 42

This will result in a SyntaxError: invalid character in identifier, because variable names cannot contain spaces.

To fix this error, simply modify the identifier to remove the invalid character(s). For example:

my_variable = 42

Or:

myVariable = 42
