读取CSV文件: 读取CSV文件: 这里的'file.csv'是你要读取的CSV文件的路径。 分隔数据: 分隔数据: 这里的'column_name'是你要分隔的列名,'separator'是你要使用的分隔符。通过str.split()函数可以将指定列中的数据按照指定的分隔符进行分隔,并使用expand=True参数将分隔后的数据展开为多列。

(可选)设置to_csv方法中的其他参数: to_csv方法还提供了许多其他参数,用于自定义CSV文件的格式。例如,可以指定分隔符(sep参数)、编码(encoding参数)等。 python df.to_csv('data_with_custom_separator.txt', sep=';', index=False, encoding='utf-8') 在上述代码中,将分隔符设置为分号(;),并将编码设...
Here, the separator character (,) is called a delimiter. There are some more popular delimiters. E.g.: tab(\t), colon (:), semi-colon (;) etc. Suppose that we are given a DataFrame that contains some float values and we need to convert it into a CSV file while maintaining the...
read_csv和read_table的区别在于separator分隔符。csv是逗号分隔值(Comma-Separated Values),仅能正确读入以 "," 分割的数据。 pd.read_table("ex1.csv", sep=",") 是否读取文本数据的header:header= headers = None表示使用默认分配的列名,一般用在读取没有header的数据文件。
