# coding=utf-8 # 打印消息,print默认会在末尾添加换行符 print("Hello, World!") print("I'm Aaron") figure 1.png 变量类型 Numbers 数字 Python 3的数字类型具体有:int整型、float浮点型、bool布尔型、complex复数。特别地: Python 2中有int、long类型。而在Python 3没有long类型,且对int类型没有大小限...
这两处设置在python的str,unicode对象的encode和decode方法中,有非常重要的作用,直接影响到结果。下面的代码按照目前的设置进行,即defaultencoding为ascii,coding为utf-8 str和unicode str是普通字符串,使用一般需要解码成unicode。unicode是unicode 字符串,默认使用unicode方式编码,使用一般需要解码成指定的格式。
如果大家想看原版的,可以去这个网址看(https://docs.python.org/2/library/stdtypes.html#string-methods),但是这里是我自己的实践以及一些理解。 1.str.capitalize() 返回第一个字母大写的str str = "a string" str.capitalize() 'A string' 1.
