      Hello Dear! Here is a little task for us in python.\

\

1] Write a program to find the sum of the data structure below\

[[1,2,3],[4,5,6,7],[8,9]]\

\

2] Write a program to convert the tuple to a dictionary where\

name is the key and age is the value. Example: x = ('John', 23, 'm'), ('Peter', 43, 'm')\

then the output will be y = {'John': 23, 'Peter': 43}.")

print()

print("Solution")

print("Task Number 1")

a = [[1,2,3],[4,5,6,7],[8,9]]

print("Using a for loop")

b = []

for i in range(len(a)):

    for j in range(len(a[i])):

        b.append(a[i][j])

print("The sum of the list of lists = ", sum(b))

print()

print("Alternatively: using list comprehension")

c =[sum(a[i]) for i in range(len(a))]

print("The sum of the list of lists = ", sum(c))

print()

print("Or")

print()

d = sum([sum(a[i]) for i in range(len(a))])

print("The sum of the list of lists = ", d)

print()

print("Solution")

print("Task Number 2")

x = ('John', 23, 'm'), ('Peter', 43, 'm')

print("Using a for loop")

y = dict()

for name, age, sex in x:

    y[name] = age

print("The new dictioary is:\n", y)

print()

print("Alternatively: using dictionary comprehension")

print()

y2 = {name:age for name, age, sex in x}

print("The new dictioary is:\n", y2)

The screen above should be the answer you get when you run the code.

Thanks.
