Odd behavior with pandas and to_csv

Question

I ran into an interesting thing today with using pandas to_csv() that I'm not sure is intended behavior. I thought I'd put it up here and see if anyone had any thoughts.

I had a data set with some text in it and some utf-8 encoded characters.

import pandas as pd
df = pd.read_csv('file',encoding='utf-8)
#Do some work
with open('file','w') as f:
    pd.to_csv(f , encoding ='utf-8')

This would throw an ascii encoding error that made me feel like an idiot If I switched to this pattern :

file_out = 'file.csv'
pd.to_csv(file_out,encoding = 'utf-8')

Worked just fine.

Any ideas if this is intended behavior ?

Answer 1

You're missing the closing quote.

import pandas as pd
df = pd.read_csv('file.csv', encoding='utf-8')

with open('file.csv', 'w') as f:
    pd.to_csv(f, encoding='utf-8')  

Additionally, you should not add spaces between the parameters and passed values. Also, add the file ending to the file you are passing.
