Python Practice Problems

Python practice problems help beginners to become experts in a python programming language with a small amount of practice effort.

Total number of special characters in a string

by

In this program, we will find the total number of special characters in a string.

Steps to solve the program
  1. Take a string as input and create another string of special characters.
  2. Create a variable to count the total number of special characters in a string.
  3. Use for loop to iterate over each character of the input string.
  4. If that character is in the string containing special characters then add 1 to the variable that we have created.
  5. Print the output.
				
					str1 = '@sqa#tools!!'
special_char = '!@#$%^&*()_{[}]'
special = 0

for char in str1:
    if char in special_char:
        special += 1
        
print("Special character: ",special)

Output :

				
					Special character:  4

add even numbers in an empty list from a given list

Print the days in a week except for Sunday

by

In this program, we will print the days in a week except for Sunday.

Steps to solve the program
  1. Take a list of days as input.
  2. Use for loop to iterate over each day in the list.
  3. If the iterated day is not Sunday then print the day.
  4. use the If statement for this purpose.
				
					days = ["Sunday","Monday","Tuesday","Wednesday","Thursday"
       ,"Friday","Saturday"]

for day in days:
    if day != "Sunday":
        print(day, end=" ")

Output :

				
					Monday Tuesday Wednesday Thursday Friday Saturday

by

In this program, we will print certain numbers.

Steps to solve the program
  1. Use for loop to iterate over numbers from 1-10.
  2. Print all the numbers except 5 and 6.
  3. Use If statement for this purpose.
				
					
for i in range(1,11):
    if i != 6 and i != 5:
        print(i,end="\n")

Output :

				
					1

Find the multiplication of natural numbers

by

In this program, we will find the multiplication of natural numbers using Python.

Steps to solve the program
  1. Create a count variable and assign its value equal to 1.
  2. Create a product variable and assign its value equal to 1.
  3. While the value of the count variable is less than 11 multiply the product variable by the count variable.
  4. Add 1 to the count variable after each iteration.
  5. Print the output.
				
					count = 1
product = 1

while count<11:
    product *= count
    count += 1
    
print("Total: ",product)

Output :

				
					Total:  3628800

Find the sum of natural numbers using Python

by

In this program, we will find the sum of natural numbers using Python.

Steps to solve the program
  1. Create a count variable and assign its value equal to 1.
  2. Create a total variable and assign its value equal to 0.
  3. While the value of the count variable is less than 11 add the count variable to the total.
  4. Add 1 to the count variable after each iteration.
  5. Print the output.
				
					count = 1
total = 0

while count<11:
    total += count
    count += 1
    
print("Total: ",total)

Output :

				
					Total:  55

Next

multiplication of the first 10 natural numbers

Program to print a table using while loop

by

In this program, we will print a table using while loop in Python.

Steps to solve the program
  1. Create a count variable and assign its value equal to 1.
  2. While value of the count variable is less than 11 multiply the count variable by 2 and store the value in another variable.
  3. Add 1 to the count variable after each iteration.
  4. Print the output.
				
					count = 1

while count < 11:
    a = count*2
    print(count,"*",2,"=",a)
    count += 1

Output :

				
					1 * 2 = 2
2 * 2 = 4
3 * 2 = 6
4 * 2 = 8
5 * 2 = 10
6 * 2 = 12
7 * 2 = 14
8 * 2 = 16
9 * 2 = 18
10 * 2 = 20
