Example
import pandas as pd
# A dataframe
df = pd.DataFrame({'Day': ['mon', 'tue', 'wed', 'thu', 'fri'],'Subject': ['Math', 'english', 'science', 'music', 'games']})
df['Day'] = df['Day'].str.upper()
print(df)Output
Running the above code gives us the following result −
Day Subject 0 MON Math 1 TUE english 2 WED science 3 THU music 4 FRI games
