- Create a variable called
number_of_dots
and set it equal to a value to start - Display the value of the variable using the
print()
function - Use a for loop to display the variable and change its value 5 times
Challenge 1.4
Challenge Level: Beginner
Write a program to display numbers 1, 2, 4, 8 and 16 on the screen one at a time. This challenge builds on the previous one, but the program should use a loop, so it could easily be updated to display more numbers.
number_of_dots
and set it equal to a value to startprint()
function# Print a string directly
print("Hello World!")
# Print a variable
print(my_var)
# Set a variable as a string
fruit_name = "Apple"
# Set a variable as an integer
pieces_of_fruit = 7
# Set a variable from a calculation
cost_of_fruit = pieces_of_fruit * cost_per_item
# Add one to a value
pieces_of_fruit += 1
# Find out the discount on fruit
if pieces_of_fruit > 100:
print("Bulk discount applies")
elif pieces_of_fruit > 5:
print("Discount applies")
else:
print("No discount")
# Print numbers 0-9 - remember Python starts counting from 0
for num in range(10):
print(num)
# Print numbers 0-9 using a while loop and a variable
num = 0
while num < 10:
print(num)
# Increment the variable by one.
# It will prevent an infinite loop!
num += 1
# Create a list of fruit
fruit = ["Apple", "Banana", "Orange", "Pear"]
# Create a function which prints a greeting
def greeting(name):
print("Hello " + name)
# Call the function
greeting("Spiderman")
