But it doesn't work.

my code is here

Answer 1

You can use:

data['Wage']=data['Wage'].replace("K","",regex=True)

Or:

data['Wage']=data['Wage'].astype(str).str.replace("K","")

Answer 2

You can also use:

df = pd.DataFrame({'Wage': ['$200k', '$500']})
df['Wage'] = df['Wage'].str.split('k', expand=True)[0]
print(df)

Output:

   Wage
0  $200
1  $500

OR

df['Wage'] = df['Wage'].str.replace(r'k', '')
print(df)

Output:

   Wage
0  $200
1  $500
