Python
1 注解与字符串的关系
1.1 Python的注解与字符串
– Python使用“#”字符注释(注释从“#”开始延伸到物理行末)
– “#”字符后面的内容会被程序负略(不被执行)
– 注释字符“#”不能包含在字符串中,包含则被当做字符串处理
1.2 实操理解
# python Python 2.7.5 (default, Aug 4 2017, 00:39:18) [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> # this is the first comment ... spam = 1 # and this is the second comment >>> # ... and now a third! ... text = "# This is not a comment because it's inside quotes." >>> print spam 1 >>> print text # This is not a comment because it's inside quotes. >>> quit()
注:
– 程序第一至三行字符“#”后面的内容被负略
– 程序第三行由于字符“#”包含在双引号中,所以字符“#”被当做普通字符处理,没有起到注释的作用
