Apply uppercase to a column in Pandas dataframe
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
