There are two ways to access a specific column in a Pandas DataFrame:<\/p>\n

    \n
  1. You can access the data of a specific column in a DataFrame by using DataFrame[column]. For example, if a DataFrame has a column named “column_name”, you can use DataFrame[‘column_name’] to retrieve the data in that column.<\/li>\n
  2. You can use DataFrame.column to access the data in a column of a DataFrame if the column name is a valid Python variable name. For example, if a DataFrame has a column named “column_name”, you can use DataFrame.column_name to retrieve the data in that column.<\/li>\n<\/ol>\n

    Here is an example code demonstrating how to access a specific column of data in a DataFrame:<\/p>\n

    import<\/span> pandas as<\/span> pd\r\n\r\n# \u521b\u5efa\u4e00\u4e2a\u793a\u4f8b DataFrame<\/span>\r\ndata = {'column1'<\/span>: [1<\/span>, 2<\/span>, 3<\/span>, 4<\/span>, 5<\/span>],\r\n        'column2'<\/span>: ['a'<\/span>, 'b'<\/span>, 'c'<\/span>, 'd'<\/span>, 'e'<\/span>]}\r\ndf = pd.DataFrame(data)\r\n\r\n# \u4f7f\u7528 DataFrame[column] \u83b7\u53d6\u67d0\u4e00\u5217\u6570\u636e<\/span>\r\ncolumn1_data = df['column1'<\/span>]\r\nprint<\/span>(column1_data)\r\n\r\n# \u4f7f\u7528 DataFrame.column \u83b7\u53d6\u67d0\u4e00\u5217\u6570\u636e<\/span>\r\ncolumn2_data = df.column2\r\nprint<\/span>(column2_data)\r\n<\/code><\/pre>\n
    In the above examples, df[‘column1’] and df.column2 respectively retrieve the data of columns ‘column1’ and ‘column2’ in DataFrame df.<\/p>\n","protected":false},"excerpt":{"rendered":"
