Create a column using for loop in Pandas Dataframe

# importing pandas

import pandas as pd

  

# Creating new dataframe

initial_data = {'First_name': ['Ram', 'Mohan', 'Tina', 'Jeetu', 'Meera'], 

                'Last_name': ['Kumar', 'Sharma', 'Ali', 'Gandhi', 'Kumari'], 

                'Marks': [12, 52, 36, 85, 23] }

  

df = pd.DataFrame(initial_data, columns = ['First_name', 'Last_name', 'Marks'])

  

# Generate result using pandas

result = []

for value in df["Marks"]:

    if value >= 33:

        result.append("Pass")

    elif value < 0 and value > 100:

        result.append("Invalid")

    else:

        result.append("Fail")

       

df["Result"] = result   

print(df)
