Applying uppercase to a column in pandas dataframe

Question

I\'m having trouble applying upper case to a column in my DataFrame.

dataframe is df.

1/2 ID is the column head that need to apply

Answer 1

If your version of pandas is a recent version then you can just use the vectorised string method upper:

df['1/2 ID'] = df['1/2 ID'].str.upper()

This method does not work inplace, so the result must be assigned back.
