Here are 30 Python challenge exercises covering the topics we have done so far:
((10 + 3) * 2 - 4 / 2) and explain the operator precedence used.
- Write a program to calculate the area of a triangle given its base and height using multiplication and division operators.
#to calculate the area of a triangle
#halve multiply by base multiply by height
base = input("choose a number of your choice?\n")
height = input("choose a second number of your choice?\n")
input_1 = 1 / 2
multiplicationOperator = input_1 * int(base) * int(height)
print(f"The quotient of {base} by {height} by {input_1} is: {multiplicationOperator}\n")
3. Evaluate the expression
((10 + 3) * 2 - 4 / 2)and explain the operator precedence used.
#using BODMAS
additionOperator = 10 + 3 #solving the bracket first
divisionOperator = 4 / 2 #solving division next after bracket
multiplicationOperator = int(additionOperator) * 2 #solving multiplication after division
subtractionOperator = int(multiplicationOperator) - int(divisionOperator) #solving subtraction last to get the final answer
print(f"The answer is: {subtractionOperator}\n") #print the value
n times, where n is a user-provided integer.4. Create a program that asks for the user’s first and last name and prints them together using string concatenation.
name = input("write your first name?\n")
Surname = input("write your surname?\n")
fullname = ("my name is " + Surname.title() + " " + name.title())
print(f"{fullname}\n")
6. Convert a floating-point number to an integer and a string. Print the results.
float_no = float(input("write down a number\n"))
int_no = int(float_no)
string = (int_no)
print(f"converted to string: {int_no}\n")
print(f"The integer number of the float number is: {string}\n")
len() Functionlen() function to check the length of a password and display whether it is “Weak”, “Moderate”, or “Strong”.7. Write a program that takes a user’s full name as input and prints the number of characters in their name.
name = input("write your name?\n") #User input his/her name
fullname = name
Tname = print(len(fullname)) #computer prints the total values of the name eg: akachukwu = 9
print(f"{Tname}\n") #computer prints it in a new line using the dictionary above in line 37
8. Create a program that asks for the user’s age and calculates the year they were born.
age = input("what's your age?\n")
year = 2024
birth = int(year) - int(age)
print(f"the year you were born is: {birth}\n")
== and = by writing a small program with both.10. Write a program to check if a given number is greater than, less than, or equal to 50.
value = input("write a value of your choice?\n") #user is ask to write a value
value_1 = 50 #computers comparing value is 50
greater = int(value) > int(value_1) #it is compared using comparism sign
lesser = int(value) < int(value_1)
if greater:
print(f"{value} is greater") #using conditional statement to compare
elif lesser:
print(f"{value} is lesser")
else:
print(f"{value} is equal")
11. Take two inputs from the user and compare if the first input is lexicographically smaller than the second.
input1 = input("Enter the first string\n")
input2 = input("Enter the second string\n")
# Compare the strings lexicographically
if input1 < input2:
print(f"'{input1}' is lexicographically smaller than '{input2}'.")
elif input1 > input2:
print(f"'{input1}' is lexicographically greater than '{input2}'.")
else:
print(f"'{input1}' is lexicographically equal to '{input2}'.")
12. Demonstrate the difference between
==and=by writing a small program with both.
13. Write a program to check if a number is divisible by both 3 and 5Write a program to check if a number is divisible by both 3 and 5
no = int(input("write a number: "))
modulusOperator = no % 3 == 0
modulusOperator2 = no % 5 == 0
if modulusOperator and modulusOperator2 is True:
print(f"{no} is divisible by 3 and 5")
else:
print(False)
14. Take three user inputs and check if all of them are non-negative numbers using boolean operators.
no1 = float(input("write a number: "))
no2 = float(input("write a second number: "))
no3 = float(input("write a third number: "))
num1 = no1 >= 0
num2 = no2 >= 0
num3 = no3 >= 0
if num1 and num2 and num3 is True:
print("all numbers are non negative")
else:
print("some numbers are negative")
15. Combine comparison and boolean operators to check if a number is between 10 and 20 (inclusive).
no_input = int(input("write a number: "))
if 10 <= no_input <= 20:
print("it is inclusive")
else:
print("it is not inclusive")
for loop.while loop that counts down from 10 to 0 and prints “Liftoff!” at the end.continue statement.for loop and break to stop iterating through a list of numbers when you find a negative number.while loop.for loop to generate a multiplication table for a number input by the user.for loop.while loops to keep asking until they guess correctly.AI Upskilling Workshops for Professionals in Non-Tech Fields: Bridging the Gap Between AI and Daily…
