Iterate Over Pandas Dataframe Using Itertuples

I am iterating over a pandas dataframe using itertuples. I also want to capture the row number while iterating: for row in df.itertuples(): print row['name'] Expected output :

Solution 1:

When using itertuples you get a named tuple for every row. By default, you can access the index value for that row with row.Index.

If the index value isn't what you were looking for then you can use enumerate

for i, row in enumerate(df.itertuples(), 1):
    print(i, row.name)

enumerate takes the place of an ugly counter construct

Solution 2:

for row in df.itertuples():
    print(getattr(row, 'Index'), getattr(row, 'name'))

Solution 3:

For column names that aren't valid Python names, use:

for i, row in enumerate(df.itertuples(index=False)):
    print(str(i) + row[df.columns.get_loc('My nasty - column / name')])

If you don't specify index=False, the column before the one named will be read.
