Expert Solution
Python Program

#1.
a = input()
#Count the length of string.
length = len(a)
print("Length:", length)
#Count the occournace of letter ‘B”
occ =  a.count('B')
print("Occurances of 'B':", occ)
#Count the total number of characters without the space in the above string.
sp =  a.count(' ')
print("Number of characters without the space:", (length - sp))
print()

#2.
#Convert the string "I am James Bond" to all uppercase and lowercase characters.
x = a.upper()
y = a.lower()
print(x)
print(y)
#Split the string "I am James Bond"
lst = a.split()
print(lst)
print()

#3.
print(type(a.split()))
print()

#4.
#Create a new variable a1, and assign “he , is, a, good, boy”.
a1 = "he , is, a, good, boy"
#Split based on the “,” delimited
x1 = a1.split(',')
print(x1)
#Split the string to the maximum of 0, 1, and 2 numbers.
j = a1.split(',' , 0)
k = a1.split(',' , 1)
l = a1.split(',' , 2)
print(j)
print(k)
print(l)
