Python does not allow punctuation characters such as @, $, and % within identifiers. Python is a case sensitive programming language. Thus,Manpowerandmanpowerare two different identifiers in Python. Here are naming conventions for Python identifiers − Class names start with an uppercase letter....
int - 整型(整数), 例如: 10, -100, 123, 0, +321 (python2.x中有long) float - 浮点型(小数), 例如: 12.5, 100.12, -3.1415926 ** str - 字符串**, 例如: '今天天气真好!', 'hello!', '123'... bool - 布尔,值只有True和False两个,Ture - 真、成立、肯定 False - 假、不成立、否定...
