Solution Exercise 2: python algorithm that swaps the first element of a list with the last

Exercise 2

Write a Python algorithm to swap the first element with the last element of a given list. Example: if L = ["Python", "Java", "C++", "Javascript"], the algorithm returns the list: ["Javascript", "Java", "C++", "Python"]

Solution

def swapList(L):
     # get the last item in the list
     swap = L[-1]
    
     # replace the last item in the list with the first
     L[-1] = L[0]
    
     # replace the first item in the list with the last
     L[0] = swap
     return L
    
# Example
L=["Python", "Java", "C++", "Javascript"]
print(swapList(L))
# Output is: ['Javascript', 'Java', 'C++', 'Python']

def swapList(L):

# get the last item in the list

swap = L[-1]

# replace the last item in the list with the first

L[-1] = L[0]

# replace the first item in the list with the last

L[0] = swap

return L

# Example

L=["Python", "Java", "C++", "Javascript"]

print(swapList(L))

# Output is: ['Javascript', 'Java', 'C++', 'Python']
