Read a text file with Python

Question

I have a text file with two million rows:

adsh    tag version coreg   ddate   qtrs    uom value   footnote
0001065088-20-000018    DecreaseInUnrecognizedTaxBenefitsIsReasonablyPossible   us-gaap/2018        20200331    0   USD 19000000.0000

You can see that this text file has 9 columns and, in the first rows there are only 7 columns. This is because there are other rows with 9 columns. I need to write a MySQL database with every row but I have to take into account the NULL values like this:

adsh                    tag                                                     version       coreg                  ddate      qtrs    uom  value          footnote
0001065088-20-000018    DecreaseInUnrecognizedTaxBenefitsIsReasonablyPossible   us-gaap/2018   NULL                  20200331   0       USD  19000000.0000  NULL
0001002910-20-000115    OtherAmortizationOfDeferredCharges                      us-gaap/2018   UnionElectricCompany  20200331   1       USD  23000000.0000  NULL

How can I make it?

Answer 1

with open ("filename.txt", 'r') as nametxt; Text = (nametext (read()); Print (Text)

Something like that
