dataframe

 Pandas DataFrame Column addition 

df = pd.DataFrame({"A": [1, 2, 3], "B": [4, 5, 6]})

 c = [7,8,9] 

df[‘C'] = c 

Column Deletion del df1['one'] 

# Deleting the first column using DEL function df.pop('two')

 #Deleting another column using POP function Rename columns 

df = pd.DataFrame({"A": [1, 2, 3], "B": [4, 5, 6]})

 >>> df.rename(columns={"A": "a", "B": "c"}) 

Pandas DataFrame Data Handling using Pandas

Row Selection, Addition, and Deletion 

#Selection by Label

 import pandas as pd1

 d1 = {'one' : pd1.Series([1, 2, 3], index=['a', 'b', 'c']), 'two' : pd1.Series([1, 2, 3, 4], index=['a', 'b', 'c', 'd'])} 

df1 = pd1.DataFrame(d1) 

print (df1.loc['b'])

Pandas DataFrame

 #Selection by integer location 

import pandas as pd1

 d1 = {'one' : pd1.Series([1, 2, 3], index=['a', 'b', 'c']), 'two' : pd1.Series([1, 2, 3, 4], index=['a', 'b', 'c','d'])}

 df1 = pd1.DataFrame(d1) 

print (df1.iloc[2])
