在进行grouped3.mean()时,我们发现报错了:DataError: No numeric types to aggregate,看一下,原来df_平均月薪列里的值都是字符型str,并不是数值型的float,因为前面的步骤没有做好,留下了这个bug,无奈我们需要对值类型做个转换。 #构造一个listi存放转化后float型的‘平均月薪’ import re pattern = re.compi...
Python considers the zero value of all numeric types falsy. All the other values are truthy, regardless of how close to zero they are.Note: Instead of a function, bool() is a class. However, because Python developers typically use this class as a function, you’ll find that most people...
Numeric values can be of integer and floating-point types. The TestComplete scripting engine does not distinguish floating-point and integer data types, so a variable can have a value of both types. Anintegervalue can accept zero, positive and negative numbers within the range ±1.7976931348623157...

In Numbers, there are mainly 3 types which include Integer, Float, and Complex. These 3 are defined as aclass in Python. In order to find to which class the variable belongs to you can use type () function. Example: a = 5 print(a, "is of type", type(a)) ...
