delim_whitespace: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True那么delimiter 参数失效。 header :指定行数用来作为列名,数据开始行数。如果文件中没有列名,则默认为0【第一行数据】,否则设置为None。如果明确设定 header = 0 就会替换掉原来存在列名。header参...

In this article, you have learned multiple ways of reading CSV files from a folder and creating one big DataFrame. Since theread_csv()function doesn’t support reading you have to load each CSV into a separate DataFrame and combine them using theconcat()function. ...
However, if your file has a different delimiter, you can specify it using the “sep” parameter, like“pd.read_csv(‘data.txt’, sep=’\t’)” for tab-separated files. Additionally, you can customize other parameters, like headers, indexes, column names, etc., according to your file’...
