python执行代码的时候会在__pycache__目录下生成对应的pyc文件, 就是python字节码文件, 这样后面执行的时候只需要看下时间戳是否能对上, 对上的话, 就没必要再转字节码了. 而这个warning是转字节码的时候告警的, 而不是执行阶段告警的. 直接执行的话, 不会生成pyc字节码, 因为Python会认为你只是偶尔执行, 没...

escape sequences are used to perform operations that aren't directly representable in string literals. for instance, you might want to insert a tab, carriage return, or a backslash into your text. since these are either invisible or conflict with the string delimiters, escape sequences allow ...
Python中的“invalid escape sequence”错误解析与解决 在Python中,当你遇到“invalid escape sequence”错误时,这通常意味着你的字符串中包含了一个无法识别的转义序列。转义序列通常用于表示那些无法直接在字符串中打印的字符,比如换行符 、制表符\t等。然而,如果字符串中的反斜杠\后跟了一个不是有效转义字符的字符...
