how to make a new column in pandas code example
Example 1: how to add new column to dataframe
# Import pandas package
import pandas as pd
# Define a dictionary containing Students data
data = {'Name': ['Jai', 'Princi', 'Gaurav', 'Anuj'],
'Height': [5.1, 6.2, 5.1, 5.2],
'Qualification': ['Msc', 'MA', 'Msc', 'Msc']}
# Convert the dictionary into DataFrame
df = pd.DataFrame(data)
# Declare a list that is to be converted into a column
address = ['Delhi', 'Bangalore', 'Chennai', 'Patna']
# Using 'Address' as the column name
# and equating it to the list
df['Address'] = address
# Observe the result
df
Example 2: how to add a new column to the pandas df
import pandas as pd
data = {'Name': ['Josh', 'Stephen', 'Drake', 'Daniel'],
'Height': [5.5, 6.0, 5.3, 4.9]}
'''
printing data at this point will show the following
Name Height
0 Josh 5.1
1 Stephen 6.2
2 Drake 5.1
3 Daniel 5.2
'''
df.insert(2, "Age", [20, 21, 20, 19])
'''
printing data now will show the following
Name Height Age
0 Josh 5.1 20
1 Stephen 6.2 21
2 Drake 5.1 20
3 Daniel 5.2 19
