Python pandas dataframe object

Question

I have a pandas dataframe with approx. 20 columns and I want to print out the values of only 4 columns to a csv file.

My python code is:

df(['statnr','agldate','stdragl','ff_pred']).to_csv("out.csv", sep=';')

I get this error message: TypeError: 'DataFrame' object is not callable

What am i doing wrong? Any hint is appreciated!

Thanks and kind regards, Alexander

You're using the wrong brackets.

df[['statnr','agldate','stdragl','ff_pred']].to_csv("out.csv", sep=';')

will do what you want. Round brackets, when following a character are reserved for function calls such as to_csv(). Therefore, Python is trying to call your dataframe as if it were a function, obviously producing an error

You should,

To PRINT,

print(df[['statnr','agldate','stdragl','ff_pred']].to_string())

To csv file,

df[['statnr','agldate','stdragl','ff_pred']].to_csv("out.csv", sep=';')
