Pandas Series – Answers

1.
import pandas as pd
EngAlph=pd.Series(['a','b','c','d','e','f','g','h','i','j','k','l','m',
                   'n','o','p','q','r','s','t','u','v','w','x','y','z'])
print(EngAlph)

2.
print(EngAlph.iloc[4:16])

3.
print(EngAlph.head(10))

4.
import pandas as pd
vow=pd.Series(0,index=['a','e','i','o','u'])
print(vow)

5.
vow.loc['a':'u']=10
print(vow)

6.
print(vow/2)

7.
vow1=pd.Series([2,5,6,3,8],index=['a','e','i','o','u'])
print(vow1)

8.
import pandas as pd
vow=pd.Series(0,index=['a','e','i','o','u'])
vow1=pd.Series([2,5,6,3,8],index=['a','e','i','o','u'])
vow3=vow+vow1
print(vow3)

9.
print(vow-vow1)
print(vow*vow1)
print(vow/vow1)

10.
vow=pd.Series(0,index=['a','e','i','o','u'])
vow.index=['A','E','I','O','U']
print(vow)

11.
print("Size:",vow.size)
print("Dimension:",vow.ndim)
print("Values:",vow.values)
