Challenge1

Create a program that asks the user for two integers (you will have to callinput() twice). The program prints the sum of the values

# Solution:

num1 = input("Enter any number below:")
num2 = input("Enter another number:")
total = int(num1) + int(num2)
print("Total is:", total)

Enter any number below: 5
Enter another number: 15


Total is: 20

Challenge2

Create a program that asks the user for two integers (you will have to call input() twice) If the value of their sum is zero, the program prints the string “Zero . Otherwise it prints the sum in integer form.

# Solution

num1 = input("Enter a number: ")
num2 = input("Enter another number: ")
total = sum([int(num1), int(num2)])

if total == 0:
    print("Zero")
else:
    print("The sum of the two numbers is:", total)

Enter a number:  5
Enter another number:  15


The sum of the two numbers is: 20

Challenge3

Create a program that asks the user integers. If the value of their sum is zero, the program prints the string “Zero”. Otherwise it prints the sum in integer form.

# Solution

def adder():
    total_sum = 0
    
    while True:
        number_input = input("Enter an integer or type done to finish:")
        if number_input == "done":
            break
            
        try:
            nums = int(number_input)
            total_sum += nums
            
        except ValueError:
            print("Please enter a valid integer")
            
    if total_sum == 0:
        print("Zero")
    else:
        print(total_sum)
        
adder()

Enter an integer or type done to finish: 5
Enter an integer or type done to finish: 15
Enter an integer or type done to finish: done

Challenge4

Create a program that asks the user for a name, and the program prints “Hello, “

# Solution

print("Hello, ", input("Enter your name below: ")+"!.")

Enter your name below:  Cyrus Baruc


Hello,  Cyrus Baruc!.

Challenge5

Create a program that asks the user for a name. If the number of characters in the name of the person is less than 7 the program prints “Hello, {name} . Otherwise it prints “Hi, {name}”

# Solution

name = input("Enter your name: ")

if len(name) < 7:
    print("Hello", name)
else:
    print("Hi", name + "!")

Enter your name:  Cyrus Baruc


Hi Cyrus Baruc!

Challenge6

Create a program that asks the user for n names. After collecting names, print the following for every inputted name: If the number of characters in the name of the person is less than , the program prints “Hello {name “. Otherwise it prints “Hi {name}”

# Solution

def greeter():
    names = []

    while True:
        name = input("Enter a name (or type 'done' to finish): ")
        if name.lower() == "done":
            break
        names.append(name)
    
    for name in names:
        if len(name) < 7:
            print(f"Hello, {name}!")
        else:
            print(f"Hi, {name}!")

greeter()

Enter a name (or type 'done' to finish):  Natalia
Enter a name (or type 'done' to finish):  Serene
Enter a name (or type 'done' to finish):  Cyanna
Enter a name (or type 'done' to finish):  Louise
Enter a name (or type 'done' to finish):  Joy
Enter a name (or type 'done' to finish):  Cyrus
Enter a name (or type 'done' to finish):  Andiana
Enter a name (or type 'done' to finish):  Dodong
Enter a name (or type 'done' to finish):  done


Hi, Natalia!
Hello, Serene!
Hello, Cyanna!
Hello, Louise!
Hello, Joy!
Hello, Cyrus!
Hi, Andiana!
Hello, Dodong!

Challenge7

Create a program that asks the user for a float. The program prints the conversion of the number to Fahrenheit

# Solution

cel = float(input("Enter a temperature in celcius from 0 to 100:"))
far = cel * (9/5) + 32
print(f"This is equivalent to {far:.2f} degrees farenheit.")

Enter a temperature in celcius from 0 to 100: 35


This is equivalent to 95.00 degrees farenheit.

Challenge8

Create a program that asks the user for a float. The program prints the conversion of the number to Fahrenheit. If the value is below the freezing point of water, the program prints “ {fahrenheit} degrees Fahrenheit cold”. If the value is above the boiling point of water, the program prints “ {fahrenheit} degrees Fahrenheit hot”. Otherwise the program prints “{fahrenheit} degrees Fahrenheit”

# Solution

num = float(input("Enter a number:"))
result = (num * (9/5)) + 32
if result <= 32:
	print(f"{result}", " degrees Fahrenheit cold")
elif result >= 212:
	print(f"{result}", " degrees Fahrenheit hot")
else:
    print(f"{result}"," degrees Fahrenheit")

Enter a number: 50


122.0  degrees Fahrenheit

Challenge9

Create a program that asks the user for three floats. The program prints the arithmetic mean of the number.s

# Solution

num1 = float(input("Enter any number: "))
num2 = float(input("Enter another number: "))
num3 = float(input("Lastly, enter another number: "))
numlist = [num1,num2,num3]
mean = sum(numlist) / len(numlist)

print(f"The mean of the numbers is {mean}.")

Enter any number:  4
Enter another number:  5
Lastly, enter another number:  6


The mean of the numbers is 5.0.

Challenge10

Create a program that asks the user for three floats. If the mean is positive, print “Negative mean” If the mean is negative, print “Positive mean” If the mean is zero, print “Zero mean”

# Solution

_num1 = input("Enter a number: ")
_num2 = input("Enter another number: ")
_num3 = input("Lastly, enter another number: ")
_mean = sum([int(_num1), int(_num2), int(_num3)])/ len([int(_num1), int(_num2), int(_num3)])
_mean = round(_mean,2)
if _mean > 0:
	print(f"{_mean} : Positive mean")
elif _mean < 0:
	print(f"{_mean} : Negative mean")
else: 
	print(f"{_mean} : Zero mean")

Enter a number:  -50
Enter another number:  59
Lastly, enter another number:  99


36.0 : Positive mean

Challenge10

Create a program that asks the user for floats. If the mean is positive, print “Negative mean”. If the mean is negative, print “Positive mean”. If the mean is zero, print “Zero mean”.

    numbers = []    
    while True:
        user_input = input("Enter a float (or type 'done' to finish): ")
        if user_input.lower() == 'done':
            break
        try:
            number = float(user_input)
            numbers.append(number)
        except ValueError:
            print("Please enter a valid float.")
    
    if len(numbers) > 0:
        mean_value = sum(numbers) / len(numbers)
        
        if mean_value > 0:
            print("Positive mean")
        elif mean_value < 0:
            print("Negative mean")
        else:
            print("Zero mean")
    else:
        print("No numbers were entered.")

mean_calculator()

Positive mean

Challenge11

Create a program that asks a user for a string and an integer. The program prints the string repeated n-times (where is the number inputted by the user).

# Solution

string = input("Enter a string: ")
integer = int(input("Enter an integer: "))

print(string * integer)

Enter a string:  ha
Enter an integer:  5


hahahahaha

Challenge12

Create a program that asks a user for a string and an integer. The program prints the string repeated -times (where is the number inputted by the user). If the number of characters in the repeated string is greater than 20,the prints “Too long, cannot print” instead.

# Solution

input_1 = input("Enter a string: ")
input_2 = input("Enter a number: ")
result = input_1 * int(input_2)
if len(result) > 20:
	print("Too long, cannot print")	
else:
	print(result)

Enter a string:  The quick brown fox jumps over the lazy dog.
Enter a number:  10


Too long, cannot print
