有时候,CSV文件可能使用除逗号以外的分隔符,可以使用sep参数来指定分隔符。 import pandas as pd # 使用分号作为分隔符读取CSV数据 df = pd.read_csv('data_semicolon.csv', sep=';') 跳过行和指定列 可以使用skiprows参数来跳过文件的一些行,以及使用usecols参数选择要读取的列。 import pandas as pd # 跳过...

By default CSV file is created with a comma delimiter, you can change this behavior by usingsepparam (separator) and chose other delimiters like tab (\t),pipe (|)e.t.c. # Using Custom Delimiter df.to_csv("c:/tmp/courses.csv", header=False, sep='|') ...
For this task, we can use the sep argument as shown below. In this specific case, we are using a semicolon instead of a comma as separator: data_import_sep=pd.read_csv('data.csv',# Import CSV filesep=';')print(data_import_sep)# Print imported CSV file ...
