Q.2 What do you understand by axes in a
NumPy array? Define axes for a 2D ndarray?
Q.3 How is Series data structure
different from a dataframe data structure?
Q.4 Write code to create a Series object
using the Python sequence [1, 3, 5, 7, 9]. Assume that Pandas is imported as
alias name pd.
Q.5 Write a program to create a Series
object using individual character ‘p’, ‘y’, ‘t’, ‘h’, ‘o’, and ‘n’. Assume that
Pandas is imported as alias name pd.
Q.6 Write a program to create a Series
object using six different words : ‘I’, ‘am’, ‘student’, ‘of’, ‘Takshila’.
Assume that Pandas is imported as alias name pd.
Q.7 Write a program to create a Series
object using an ndarray that has 5 elements in the range 35 to 70.
Q.8 Write a program to create a Series
object using an ndarray that is created by tilling a list [7, 5] twice.
Q.9 Write a program to create a Series
object using a dictionary that stores the number of students in each section
(A, B, C, D, E) of class XII in your school
Q. 10 Write a program to create a Series
object that stores the initial budget allocated (75000/- each) for the 4
quarters of the year : Qtr1, Qtr2, Qtr3 and Qtr4.
Q.11 A Python list namely section stores
the section names (‘A’, ‘B’, ‘C’, ‘D’, ‘E’) of class XII in Takshila Academy.
Another list contri stores the contribution made by these students to a charity
fund endorsed by the school. Write code to create a Series object that stores
the contribution amount as the values and the section names as the indexes.
Q.12 Consider
the Series object ser1 that stores
the contribution of each section, as shown below:
A 7500
B 9500
C 6892
D 7800
E 5600
Write code to modify the amount of Section ‘B as 10700 and for the section ‘D’ and ‘E’ as
