python - 将文本文件转换为 Pandas 数据框

Question

我有 .TX0 文件(某种 csv txt 文件)并通过 python .readlines()、open(filename, 'w') 等方法将其转换为 .txt 文件。我有这个新保存的 txt 文件，但是当我尝试将它转换为数据框时，它只给我一列。 txt 文件如下:

Empty DataFrame
Columns: [ '"Software Version:", 6.3.2.0646, Date:, 19/08/2015 09:26:04\n',  '"Reprocess Number:", vma2:  261519, Unnamed: 7, \n',  '"Sample Name:",  , Data Acquisition Time:, 18/08/2015 17:23:23\n',  '"Instrument Name:", natural gas (PE ASXL-TCD/FID), Channel:, B\n',  '"Rack/Vial:", 0, 0.1, Operator:, joey.walker\n',  '"Sample Amount:", 1.000000, Dilution Factor:, 1.000000\n',  '"Cycle:", 1, Result File :, \\\\vma2\\TotalChrom\11170_he_tcd001.rst \n',  '"Sequence File :", \\\\vma\C1_C2_binary.seq \n',  '"===================================================================================================================================="\n',  '""\n',  '""\n'.1,  '"condensate analysis (HP4890 Optic - FID)"\n',  '"Peak", Component, Time, Area, Height, BL\n',  '"#", Name, [min], [uV*sec], [uV], \n'.1,  '------, ------, ------.1, ------.2, ------.3, ------\n',  '1, Unnamed: 55, 0.810, 706.42, 304.38, *BB\n',  '2, CH4, 0.900, 1113518.24, 495918.41, *BB\n'.1,  '3, C2H6, 1.373, 901670.23, 295381.12, *BB\n'.2,  '"", Unnamed: 73, Unnamed: 74, ------.4, ------.5, \n'.2,  '"".1, Unnamed: 79, Unnamed: 80, 2015894.89, 791603.91, \n'.3,  '"Missing Component Report"\n',  '"Component", Expected Retention (Calibration File)\n',  '------.1, ------\n'.1,  '"All components were found"\n',  '"Report stored in ASCII file :", C:\\Shared Folders\\TotalChrom\\11170_he_tcd001.TX0 \n']]
Index: []

为了便于阅读:

Empty DataFrame

Columns: [ '"Software Version:", 6.3.2.0646, Date:, 19/08/2015 09:26:04\n', '"Reprocess Number:", vma2: 261519, Unnamed: 7, \n', '"Sample Name:", , Data Acquisition Time:, 18/08/2015 17:23:23\n', '"Instrument Name:", natural gas (PE ASXL-TCD/FID), Channel:, B\n', '"Rack/Vial:", 0, 0.1, Operator:, joey.walker\n', '"Sample Amount:", 1.000000, Dilution Factor:, 1.000000\n', '"Cycle:", 1, Result File :, \\vma2\TotalChrom\data\Joey\Binary_Mixtures\Std1\11170_he_tcd001.rst \n', '"Sequence File :", \\vma2\TotalChrom\sequences\Joey\C1_C2_binary.seq \n', '"===================================================================================================================================="\n', '""\n', '""\n'.1, '"condensate analysis (HP4890 Optic - FID)"\n', '"Peak", Component, Time, Area, Height, BL\n', '"#", Name, [min], [uV*sec], [uV], \n'.1, '------, ------, ------.1, ------.2, ------.3, ------\n', '1, Unnamed: 55, 0.810, 706.42, 304.38, *BB\n', '2, CH4, 0.900, 1113518.24, 495918.41, *BB\n'.1, '3, C2H6, 1.373, 901670.23, 295381.12, *BB\n'.2, '"", Unnamed: 73, Unnamed: 74, ------.4, ------.5, \n'.2, '"".1, Unnamed: 79, Unnamed: 80, 2015894.89, 791603.91, \n'.3, '"Missing Component Report"\n', '"Component", Expected Retention (Calibration File)\n', '------.1, ------\n'.1, '"All components were found"\n', '"Report stored in ASCII file :", C:\Shared Folders\TotalChrom\data\Joey\Binary_Mixtures\Std1\11170_he_tcd001.TX0 \n']] Index: []

如您所见，这是逗号分隔的。是否有任何方法可以将此文本传输到逗号分隔的数据框？

谢谢。
