The string in this example opens with a single quote, so Python assumes the next single quote—the one in parentheses—is the closing delimiter. The final single quote is then a stray, which causes the syntax error shown.If you want to include either type of quote character within the ...
delimiter: str, default None 定界符,备选分隔符(如果指定该参数,则sep参数失效) delim_whitespace: boolean, default False. 指定空格(例如’ ‘或者’ ‘)是否作为分隔符使用,等效于设定sep='\s+'。如果这个参数设定为Ture那么delimiter 参数失效。
read_csv()读取文件 1.python读取文件的几种方式 read_csv 从文件,url,文件型对象中加载带分隔符的数据。默认分隔符为逗号 read_table 从文件,url,文件型对象中加载带分隔符的数据。默认分隔符为制表符(“\t”) read_fwf 读取定宽列格式数据(也就是没有分隔符) ...
