Recently, while I was working with the panda’s module recently and I discovered an OverflowError: Python int too large to convert to C long. I was running a python script, where I have to convert a string column from a pandas df to int, using the astype(int) method. However, I got the error. The code was as follows:
import pandas as pd
df = pd.DataFrame({'t': ['123456789985', '178965423698']})
df['int'] = df['test'].astype('int')
print(df['int'])
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OverflowError: Python int too large to convert to C long
How can I resolve it?
