[ahmedelgabalawy]

Question 1:

Write a python program to input an alphabet and check whether it is

vowel or consonant.

Note: Vowel alphabets are: {a, e, o, u, i}

All other alphabets are consonant

vowel = {'a','e','o','u','i'}
a = input("write letter")
print(f'char {a} is vowel') if a.lower() in vowel else print(f'char "{a}" is not vowel')

Question 2:

Write a python program that prompts the user to input a number. The

program should then output this number and a message saying whether

it is even or odd

n = int(input("enter number :"))
print(f"number {n} in even") if n%2 == 0 else print(f"number {n} in odd")

Question 3:

Write a python program to input a character from user and check whether

the given character is alphabet, digit or special character

n = input("enter character :")
if n.isdigit(): print(f"'{n}' is digit")
elif n.isalpha(): print(f"'{n}' is alphabet")
else : print(f"'{n}' is special character")

Question 4:

Write a python program that prompts the user to input a number. The

program should then output this number and a message saying whether it

is positive, negative, or zero

n = int(input("Enter number : "))
if n > 0 : print("Number is Postive")
elif n < 0 : print("Number is negative")
else: print("Number is zero")

Question 5:

Write a python program of a four-function calculator.

The program should ask the user to enter a number, an operator, and another number.

It should then carry out the specified arithmetical operation: adding, subtracting,

multiplying, or dividing the two numbers.

def myfunc(num1 ,operation , num2):
    if operation == '+':
        print(f"{num1} {operation} {num2} = {num1 + num2}")
    elif operation == '-':
        print(f"{num1} {operation} {num2} = {num1 - num2}")
    elif operation == '*':
        print(f"{num1} {operation} {num2} = {num1 * num2}")
    elif operation == '/':
        print(f"{num1} {operation} {num2} = {num1 / num2}")
    else :
        print("Error no operation")

n1 = int(input("Enter frist number : "))
op = input("operation : ")
n2 = int(input("Enter second number : "))
myfunc(n1 , op , n2)

Question 6:

Write a python program that will prompt the user to input 5 integer values

to be stored in a list.

l = []
for x in range(5):
    l.append(int(input("Enter Number :")))

print(l)

Question 7:

Write a python program that print the values of a list.

l = ["python", "java" , "C++" , "PHP"]

for x in l:
    print(x)

Question 8:

Write a python program that print the values of a list in a reverse order

l = [1,2,3,4,5]
for x in l[::-1]:
    print(x)

Question 9:

Write a python program that will prompt the user to input a list of 5

integer values. Then it print their summation and average.

l = []
for x in range(5):
    l.append(int(input("Enter Number : ")))

print(f"list : {l}")
print(f"summation is : {sum(l)}")
print(f"average is : {sum(l)/5}")

Question 10:

Write a python program that will prompt the user to input a list of 5

integer values. Then it print the summation and average of its contained

even numbers.

l = []
for x in range(5):
    num = int(input("Enter Number : ")) 
    if num%2 == 0 : 
        l.append(num)

print(f"summation is : {sum(l)}")
print(f"average is : {sum(l)/len(l)}")

Question 11:

Write a python program that will prompt the user to input a list of 5

integer values. Then it print its maximum and minimum values.

l = []
for x in range(5):
    l.append(int(input("Enter Number : ")))

print(f"maximum : {max(l)}" )
print(f"minimum : {min(l)}")

Question 12:

Write a python program that will prompt the user to input a list of 5

integer values. Then it ask the user to enter a number to check whether or

not this number is found in the list or not.

l = []
for x in range(5):
    l.append(int(input("Enter Number : ")))

n = int(input("enter number to check :"))
if n in l :
    print("the number is in the list")
else :
    print("the number not is in the list")

Question 13:

Write a python program that will prompt the user to input an index of a list to print its value.

lang = ["python", "java" , "C++" , "PHP"]

x = int(input("Enter index : "))

print(lang[x])

Question 14:

Write a python program that will prompt the user to input a list of 5

integer values. Then it count the number of occurrence of the given

number in such list

l = []
for x in range(5):
    l.append(int(input("Enter Number : ")))

for x in set(l):
    print(f"{x} : {l.count(x)}")

Question 15:

Write a python program that merge two lists.

lang1 = ["python", "java" ]
lang2 = [ "C++" , "PHP"]
lang3 = lang1 + lang2
print(lang3)

Question 16:

Write a python program that will prompt the user to input a list of 5

integer values. Then it splits the list into two lists; the first will contains

even numbers while the other will contain odd numbers

l = []
odd = []
even = []

for x in range(5):
    num = int(input("Enter Number : "))
    if num %2 :
        even.append(num)
    else :
        odd.append(num)

print(f"even {even}" )
print(f"odd {odd}" )

Question 17:

Write a python program that asks the user to enter an integer number then it prints its factorial

Note: factorial(n) = n(n-1)(n-2)(n-3)(n-4).......32*1

num = int(input("enter Number : "))
x = 1 
n = num
while n > 0 :
    x *= n
    n -= 1 
else :
    print(f"factorial of {num} is {x}")

Question 18:

Write a python program that asks the user to enter two integer numbers, a

and b, then it prints a power b

Note: a power b= a a a .... ( b times)

a = int(input("Enter Number : "))
b = int(input("Enter Power : "))

## solution 1
z = 1
for x in range(b):
    z *= a

print(z)

## solution 2
print(a**b)
