Answer 1

Use:

df['1'].apply(lambda x:  str(x) + '(EA)' if '(EA)' not in str(x) else x)

if the name of column not is a str then use:

df[1].apply(lambda x:  str(x) + '(EA)' if '(EA)' not in str(x) else x)

Answer 2

Try this

df['1']=df['1']+ '(EA)'

It will add (EA) to every row except for the row that has NaN

Answer 3

df_1['1'] = df_1['1'] + " (EA)"
