对于Python脚本文件本身,如果包含非UTF-8字符,通常需要在文件开头添加特殊的注释来指定编码方式。例如,如果文件是GBK编码的,我们可以在文件的第一行或第二行添加以下注释: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 #-*-coding:gbk-*-# 或者 # coding=gbkprint("你好,世界!") 但是,请注意,对于Python...

/usr/bin/env python 的注释,而非 #!/usr/bin/python。 如果是在windows环境中执行文件的话,这行注释就无所谓了,因为你在cmd中,需要先定位到你py文件所在的文件夹后,再使用python testmode.py 这样的语句来执行文件。window系统也不会去看这行注释. 2.# -*- coding:utf-8 -*- 它的作用:在Linux下指定...

As an exercise, go ahead and explore how REMAINDER works by coding a small app by yourself. Even though the nargs argument gives you a lot of flexibility, sometimes it’s pretty challenging to use this argument correctly in multiple command-line options and arguments. For example, it can be...
What if I want to manipulate or replace newlines in a text string? If you want to manipulate or replace newlines within a text string, you can use various string manipulation functions provided by the programming language. For instance, in Python, you can use the "replace()" method to repl...

一般是在语句中使用了中文输入的符号,比如括号,逗号,冒号,单引号,双引号等。 Python里面这些字符就是非法的,需要在英文状态下输入。 s = 0 for i in range(1, 6): s = s + i print( s) # 此处右括号是在中文状态输入的 # SyntaxError: invalid decimal literal ...
