Writing a dictionary to a text file?

Question

I have a dictionary and am trying to write it to a file.

exDict = {1:1, 2:2, 3:3}
with open(\'file.txt\', \'r\') as file:
    file.write(exDict)

I know this is an old question but I also thought to share a solution that doesn't involve json. I don't personally quite like json because it doesn't allow to easily append data. If your starting point is a dictionary, you could first convert it to a dataframe and then append it to your txt file:

import pandas as pd
one_line_dict = exDict = {1:1, 2:2, 3:3}
df = pd.DataFrame.from_dict([one_line_dict])
df.to_csv('file.txt', header=False, index=True, mode='a')

I hope this could help.
