用 pandas 读取文件读取 csv 不起作用

Question

All the column data is going inside the "index" column

the header starts from row number 7

'''
 index      mfg    legalId    resellerName   resellerCountry
(SONICWALL',' ','HEXAPAGE','FRANCE')                
(SONICWALL',' ','SEXTANT BTS LLC','UNITED STATES')              
(SONICWALL',' ','New Vision Networks, Inc.','UNITED STATES')
'''

All the values are inside index column, i want those values to come under specified column respectively Specified columns are

mfg, legalId, resellerName, resellerCountry

Below is the code which i have written, please help me how to do this

df2=pd.read_csv(data, header=6, keep_default_na=False, sep=',', delimiter=',', quoting=csv.QUOTE_MINIMAL)

Answer 1

if your.csv file already has columns as first row then remove header=6 argument and let it infer which is default.

If you keep "index" column in csv file then with header='infer' dataframe will look like below table which is not aligned with respect to data. As data is shifted to left because data does not have index values mentioned

+----+-----------+-------+--------------------------+----------------+-------------------+
|    | index     | mfg   | legalId                  | resellerName   | resellerCountry   |
+====+===========+=======+==========================+================+===================+
|  0 | SONICWALL |       | HEXAPAGE                 | FRANCE         |                   |
+----+-----------+-------+--------------------------+----------------+-------------------+
|  1 | SONICWALL |       | SEXTANT BTS LLC          | UNITED STATES  |                   |
+----+-----------+-------+--------------------------+----------------+-------------------+
|  2 | SONICWALL |       | New Vision Networks Inc. | UNITED STATES  |                   |
+----+-----------+-------+--------------------------+----------------+-------------------+

you can remove "index" column from.csv file and reset_index on dataframe by:

df2.reset_index(level=0, inplace=True)

and data will be:

+----+---------+-----------+-----------+--------------------------+-------------------+
|    |   index | mfg       | legalId   | resellerName             | resellerCountry   |
+====+=========+===========+===========+==========================+===================+
|  0 |       0 | SONICWALL |           | HEXAPAGE                 | FRANCE            |
+----+---------+-----------+-----------+--------------------------+-------------------+
|  1 |       1 | SONICWALL |           | SEXTANT BTS LLC          | UNITED STATES     |
+----+---------+-----------+-----------+--------------------------+-------------------+
|  2 |       2 | SONICWALL |           | New Vision Networks Inc. | UNITED STATES     |
+----+---------+-----------+-----------+--------------------------+-------------------+
