IP practical file python programs

1 Write a program to generate a series of the first 10 numbers.

import pandas as pd
def Ser_1to10():
     s = pd.Series(range(1,11))
     print(s)
Ser_1to10()

2 Write a program to generate a series of float numbers from 21.0 to 30.0 with an increment of 1.5 each.

import pandas as pd
import numpy as np
def fl_ser():
    n = np.arange(21,32,1.5)
    s = pd.Series(n)
    print(s)
fl_ser()

3 Write a program to generate a series using a dictionary to represent month number and month names.

import pandas as pd
def Ser_dic():
    di = {1:'January',2:'February',3:'March',4:'April',5:'May',6:'June',
          7:'July',8:'August',9:'September',10:'October',11:'November',12:'December'}
    s = pd.Series(di)
    print(s)
Ser_dic()

4 Write a program to generate a series of 5 elements of multiples of 7 starting with 35 with index multiply by 3. 

import pandas as pd
import numpy as np
def Ser_mul7():
    a = 35
    n = np.arange(a,a*2,7)
    s = pd.Series(index=n*3,data=n)
    print(s)
Ser_mul7()

5 Write a program to generate a series of marks of 10 students. Give grace marks up to 5 of those who are having <33 marks and print the new list of the marks.

import pandas as pd
def Ser_stumarks():
    std_marks = []
    for i in range(1,11):
        m = int(input("Enter the marks:"))
        std_marks.append(m)
    s = pd.Series(index=range(1201,1211),data=std_marks)
    s[s<33]=s+5
    print("New List is:")
    print(s[s>=33])
Ser_stumarks()

6 Write a program to generate a series of these numbers: 33,55,65,29,19,23. Find the sum of those values which ends with 3 or 5.

import pandas as pd
list = [33,55,65,29,19,23]
ser = pd.Series(list)
val_sum = 0
sum5 = sum(ser[ser % 10 == 5])
sum3 = sum(ser[ser % 10 == 3])
print(sum3+sum5)

7 Write a program to generate a series of 10 numbers. Change the value of all the elements to 21 those values are multiples of 4.

import pandas as pd
numbers = []
# Generating a series
for i in range(1,11):
    val = int(input("Enter a number :"))
    numbers.append(val)
    ser = pd.Series(numbers)
    # Changing the values of multiple of four and assigning them a value 21
ser[ser % 4 == 0] = 21
print(ser)

8 Write a program to generate a series of 10 numbers starting with 41 and with the increment of 3. Now add 7 all odd values and reprint the updated series.

import pandas as pd
s = pd.Series(range(41,71,3))
print(s)
s[s % 2 != 0] = s + 7
print(s)

9 Write a program to generate a series of 10 numbers with scalar value 33.

import pandas as pd 
print(pd.Series(33,range(1,11)))

10 Write a program to generate series S1 with prime numbers between 1 to 25 and S2 with factorial numbers between 1 to 25. 

import pandas as pd
import math
s1 = pd.Series(x for x in range(1,25)
               if all(x % y != 0 for y in range(2, x)))
s2 = pd.Series([math.factorial(n)
                for n in range(25)])
print("Prime Number series:")
print(s1)
print("Factorial series:")
print(s2)

11 Write a program to swap the values of series to modify the contents of the series that the values which are multiples of 5 with the value present at the position in the array.

Do yourself

12 Write a program to demonstrate the use of common series attributes. Generate any series of your choice.

Do yourself by using common attributes like index, size, shape etc.

13 Write a program to generate a series and print the top 3 elements using the head function.

import pandas as pd
# generating the series
ser_length = int(input("Enter the length of the series: "))
data = []
for i in range(ser_length):
    val = int(input("Enter a val:"))
    data.append(val)
    ser = pd.Series(data)
print(ser.head(3))

14 Write a program to generate a series and print the bottom 3 elements using the tail function.

Do yourself using tail() function.
