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

This should work:

df['1/2 ID'] = map(lambda x: str(x).upper(), df['1/2 ID'])

and should you want all the columns names to be in uppercase format:

df.columns = map(lambda x: str(x).upper(), df.columns)
