Python pandas: output dataframe to csv with integers

Question

I have a pandas.DataFrame that I wish to export to a CSV file. However, pandas seems to write some of the values as float instead of int

Answer 1

You can change your DataFrame into Numpy array as a workaround:

 np.savetxt(savepath, np.array(df).astype(np.int), fmt='%i', delimiter = ',', header= 'PassengerId,Survived', comments='')
