I have the foll. dataframe:
df
A B
0 23 12
1 21 44
2 98 21
How do I remove the column names A
and B
from this dataframe? One way might be to write it into a csv file and then read it in specifying header=None. is there a way to do that without writing out to csv and re-reading?
How to get rid of a header(first row) and an index(first column).
To write to CSV file:
df = pandas.DataFrame(your_array)
df.to_csv('your_array.csv', header=False, index=False)
To read from CSV file:
df = pandas.read_csv('your_array.csv')
a = df.values
If you want to read a CSV file that doesn't contain a header, pass additional parameter header
:
df = pandas.read_csv('your_array.csv', header=None)
Haven't seen this solution yet so here's how I did it without using read_csv:
df.rename(columns={'A':'','B':''})
If you rename all your column names to empty strings your table will return without a header.
And if you have a lot of columns in your table you can just create a dictionary first instead of renaming manually:
df_dict = dict.fromkeys(df.columns, '')
df.rename(columns = df_dict)
I had the same problem but solved it in this way:
df = pd.read_csv('your-array.csv', skiprows=[0])
