how to make a 'for' loop to print all even numbers between 0-100
hi i cant figure how to make a 'for' loop in python to print all even numbers between 0-100
So for loops can loop through a list. The
range() function returns a list of numbers in your range (you can try it and see), but it is not inclusive. So, to generate a list of numbers from 1-100, you would do
Now you have a list that looks something like this:
[1, 2, 3, 4, 5, ..., 100]
Your next step is to loop, so using a for loop, you would do this:
for i in range(1, 101): #stuff goes here
Now if you replaced
#stuff goes here with
print(i) it would print every number in the list from 1 to 100, but you only want even numbers.
We can check for even numbers using modulus (
The modulus returns a the remainder of an integer division, so
5 % 2 is
1 because 5 divided by 2 is 2 remainder 1.
Now we can make an if statement to make your loop only print if the number in the list is even and thus returns a 0 when it is modulus divided by 2.
Our final code is:
for i in range(0, 101): #loops if i%2==0: #checks if even print(i) #prints the even number
