"abs() takes exactly one argument (0 given)" : abs函数需要一个参数,但是只提供了0个(0 given) 2.3 索引错误:IndexError list index out of range: 列表的索引超出了范围。我们往回看变量a只有3个元素,现在取下标5,那肯定是超出范围了 2.4 零不能作为分母:ZeroDivisionError 这个是比较容易理解的 2.5 值...

The above snippet shows the error “expected string or bytes-like object”because the “list” is used as an argument of the “re.findall()” method. Solution: Use Function That Returns String To resolve this error, use a function that returns string value rather than other data types. Be...
