Python List Part-1

Q-1. Write a Python program to sum all the items in a List.

Input: [1,2,3,0,79,7]
Output: 92 (Sum of elements)

Python Code:

#sum of all elements in list

def sum_num(num_list):
    sum_list=0

 #Iterating each element in List
    for ele in num_list:
        sum_list += ele
    return sum_list

print(sum_num([1,2,3,0,79,7]))

Q-2. Write a Python program to get the largest number from a List.

Input:[1,8,3,9,4]
 
Output: 9(largest element in list)

Python Code:

#finding max element 

def max_num(num_list):
    max=num_list[0]
#Iterating the collection
    for ele in num_list:
        if ele>max:
            max=ele
    return max

print(max_num([1,8,3,9,4]))

Q-3. Write a Python program to get the smallest number from a List.

Input:[1,8,3,9,4] 

Output: 1(smallest element in list)

Python Code:

#finding min element

def min_num(num_list):

#here we took min as first element of the list.
    min=num_list[0]
    for ele in num_list:
        if ele<min:
            min=ele
    return min

print(min_num([1,8,3,9,4]))

Q-4. Write a Python program to clone or copy a List..

Input:[7,88,5,0,2] 

Output: the new list  : [7, 88, 5, 0, 2]

Python Code:

#cloning of list  

original_list=[7,88,5,0,2]
new_list=list(original_list)
print("the new list :",new_list)

Q-5. Write a python program to reverse the List.

Input:[1,2,3] 

Output: [3, 2, 1]

Python Code:

#reversing the elements of list

def reverse_lst(list1):
    n=len(list1)
    rev=[]
    for i in range(n-1,-1,-1):
        rev.append(list1[i])
        i-=1
    return rev
list1=[1,2,3]

print(reverse_lst(list1))    

Alternative way of reversing the list

#another way of reversing the elements of list
item = [10, 11, 12, 13, 14, 15] 
new_list = item[::-1] 
print(new_list)
