Convert all uppercase to lowercase in a word

In this program, we will take a word as input from the user and convert all uppercase to lowercase in a word.

Steps to solve the program

Take a word as input from the user.
Use for loop to iterate over each character of the word.
Check whether the character is uppercase or not using isupper().
If it is an uppercase character convert it to lowercase using lower().
Print the output.

Solution 1 :

				
					input1 = input("Enter word: ")
result = ''
for char in input1:
    if char.isupper():
        print(char.lower(),end="")
    else:
        print(char,end="")

Output :

				
					Enter word: SQATOOLS
sqatools

Solution 2 :

				
					str1 = input("Enter input string:")
result = ""
for char in str1:
    # get character ascii value 
    char_ascii = ord(char)
    # check ascii value between 65 - 90 range
    # then character is in upper case
    if 65 <= char_ascii <= 90:
        # get character exact location
        char_position = char_ascii - 65
        # convert upper char ascii to lower case.
        # add character to the result
        result = result + chr(97+char_position)
    else:
        result = result + char

print("Result :", result)

Output

				
					Enter Input String: SQATOOLS Learning
Result : sqatools learning

Fizz-Buzz Program

accepts a string and calculates the number of digits and letters

Print Fizz Buzz for multiples of certain numbers

In this program, we will print Fizz Buzz and FizzBuzz for multiples of certain numbers.

Steps to solve the program

Use for loop with the range function to iterate over all the numbers from 1 to 30.
If a number is multiple of 3 and 5 then print FizzBuzz.
If a number is multiple of 3 print Fizz.
If a number is multiple of 5 print Buzz.

				
					#Printing output
for i in range(1,31):
    if i%3 == 0 and i%5 == 0:
        print("FizzBuzz")
    elif i%3 == 0:
        print("Fizz")
    elif i%5 == 0:
        print("Buzz")

Output :

				
					Fizz
Buzz
Fizz
Fizz
Buzz
Fizz
FizzBuzz
Fizz
Buzz
Fizz
Fizz
Buzz
Fizz
FizzBuzz

program to get the Fibonacci series

converts all uppercases in the word to lowercase

Get the Fibonacci series between 0 to 20.

In this program, we will get the Fibonacci series between 0 to 20.

Steps to solve the program

Create two variables and assign their values equal to 0 and 1 respectively.
Create another variable count and assign its value equal to 0.
While the count variable is less than 20 print the num1.
Add num1 and num2 and assign their addition to the n2 variable.
Change the value of num1 with num2 and num2 with n2.
Add 1 to the count variable.
Print the Fibonacci series.

				
					num1 = 0
num2 = 1
count = 0

while count < 20:
    print(num1,end=" ")
    n2 = num1 + num2
    num1 = num2
    num2 = n2
    count += 1

Output :

				
					0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181

prints all the numbers from 0 to 6 except 3 and 6

Fizz-Buzz program

Print all numbers except certain numbers.

In this program, we will print all the numbers except certain numbers.

Steps to solve the program

Use for loop to print all the numbers from 1 to 10.
If the number is not equal to 3 or 6 only then print the number.

				
					for i in range(0,11):
        if i != 3 or i != 6:
            print(i,end=" ")

Output :

				
					0 1 2 4 5 7 8 9 10

count the number of even and odd numbers from a series of numbers

program to get the Fibonacci series

Count the number of even and odd numbers

In this program, we will count the number of even and odd numbers from a series of numbers.

Steps to solve the program

Take a series of numbers as input.
Create two variables even and odd and assign their value equal to 0.
Use for loop to iterate over each number from the series.
If the number is even add 1 to the even and if the number is odd add 1 to the odd.
Print the output.

				
					numbers = (1, 2, 3, 4, 5, 6, 7, 8, 9)
even = 0
odd = 0

for val in numbers:
    if val%2 == 0:
        even += 1
    else:
        odd += 1
        
print("Number of even numbers: ",even)
print("Number of odd numbers: ",odd)

Output :

				
					Number of even numbers:  4
Number of odd numbers:  5

add the word from the user to the empty string

Get a list of mobile numbers from the string

In this program, we will take a string as input and get a list of mobile numbers from the given string.

Steps to solve the program

Take a list as input.
Convert the string into a list using split() and create an empty list.
Use for loop to iterate over every word in the list.
If the length of the word is 10 and that word contains all numbers then add that word to the empty list.
Print the output.
