List of Python programs for students studying Informatics Practices and Computer Science.

 

 

Program 1: Write a program in python to accept a string and display it in reverse order.

# write a program in python to accept a string and display it in a reverse order.
str1=input("Enter a string: ")
print("Reverse string is: ",str1[::-1])

Output:

Program 2: Write a program in python to extract a list slice out of a given list of numbers from 1 to 20. Display average of elements in the slice that contains every fourth element of the list.

#Write a program in python to extract a list slice out of a given list of numbers 
# from 1 to 20. Display average of elements
# in the slice that contains every fourth
# element of the list.
a = []
for i in range(1,21):
a.append(i)
sum = 0
for element in a[::4]:
sum+=element
print(sum/5)

Output:

Program 3:Write a program in python to accept a string and check whether it is palindrome or not.

#Write a program in python to accept a string and check 
#whether it is palindrome or not.

word=input("Enter a string: ")
reverse_word = ''
for ch in word:
reverse_word = ch + reverse_word
if reverse_word == word:
print(f'{word} is a palindrome.')
else:
print(f'{word} is not a palindrome.')

Output:

Program 4:Write a program in python to calculate mean of a list of numbers.
