In the above example,\s+is a Python regular expression that matches any whitespace character (spaces, tabs, line breaks). So it splits the string into list words based on the space, or you can see the string even contains the tab‘\t’and line breaks‘\n’. This is how to use a ...
直接在python中输入中文的字符串会报编译错误SyntaxError: Non-ASCII character,因为python文件默认编码方式是ASCII。如果想要打印中文字符,有两种方式: 1.在文件第一行加入# -*- coding: UTF-8 –*-,修改文件的默认编码方式。然后直接在python 文件编辑中文字符串即可,例如:string = “中文” 2. 将需要打印的中文...
Return True if the string is a digit string, False otherwise. A string is a digit string if all characters in the string are digits and there is at least one character in the string. ''' s8 = "4567124" print(s8.isdigit()) # True 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. ...
标识符中有无效字符(invalid character in identifier) 检查到不完整的字符串(EOL while scanning string litera) 很多情况下是由于字符串两边的引号不统一。 错误示例 print('hello','world') 错误原因:逗号为中文逗号 报错信息:SyntaxError: invalid character inidentifier result = (1024+(512*2)/128 错误原因:...
