Calculate the number of digits and letters

In this program, we will accept a string and calculate the number of digits and letters.

Steps to solve the program

Take a word as input.
Create two variables to calculate the number of digits and letters and assign their values equal to 0.
Use for loop to iterate over each character from the word.
Check whether the character is a letter or a digit using isaplha() and isnumeric().
Add 1 to the corresponding variable according to the type of the charater.
Print the output.

Solution 1

				
					word = "python1234"
digit = 0
character = 0

for ele in word:
    if ele.isalpha():
        character += 1
    elif ele.isnumeric():
        digit += 1
        
print("Digits :",digit)
print("Characters: ",character)

Output

				
					Digits : 4
Characters:  6

Solution 2

				
					inputstr = 'pythons12345'
digits = '0123456789'
letters = ''
# create small case and capital case sequence with ASCII
for i in range(1, 27):
    letters = letters + chr(65+i) + chr(97+i)

digit_count = 0
letter_count = 0
# iterate over each character with loop
for word in inputstr:
    # check if word is digit and increase digit count
    if word in digits:
        digit_count += 1
    # check if word is letters and increase letter count
    elif word in letters:
        letter_count += 1


print("Digit Count :", digit_count)
print("Letter Count :", letter_count)

Output

				
					Digits Count : 5
Letter Count : 7

converts all uppercases in the word to lowercase

print the alphabet pattern ‘O’

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

        print("FizzBuzz")
    elif i%3 == 0:
        print("Fizz")
    elif i%5 == 0:
        print("Buzz")

Output :

				
					Fizz
Buzz
Fizz
Fizz
Buzz
Fizz

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
