我们使用 for 循环遍历列表并调用split()方法来拆分每个字符串。 如果我们正在读取文件并需要拆分文件中的每一行,请使用 for 循环。 withopen('example.txt','r', encoding="utf-8")asf:forlineinf:# 👇️ split line on each commaresult = line.split(',')print(result) 我们打开了一个名为example.t...
说明:字符串对象的split()只能处理简单的情况,而且不支持多个分隔符,对分隔符周围可能存在的空格也无能为力。 #example.py# #Example of splitting a string on multiple delimiters using a regeximportre#导入正则表达式模块line='asdf fjdk; afed, fjek,asdf, foo'#(a) Splitting on space, comma, and se...
咱们先构造一个无表头的 csv 文档,这里一共有两列,每列之间用“,” comma 逗号分割开来。 1. 逐行打印, 用 row 去接收split(',') withopen("names.csv",'r')asfile:forlineinfile:row=line.rstrip().split(',')print(f"student{row[0]} is in {row[1]}") ...

Alternatively, you can use the re.split() function from the re module to split a string based on a regular expression pattern that includes both a semicolon followed by a space (; ) and a comma followed by a space (, ) as delimiters....
