why does the number % 10 == 0 . D0n't understand that please explain.

def divisible_by_ten(nums):
count = 0
for number in nums:
if (number % 10 == 0):
count += 1
return count

// this is javascript, but can be used in any language
// with minor modifications of variable definitions
let array = ["foo", "bar"]
let low = 0; // the index to start at
let high = array.length; // can also be a number
/* high can be a direct access too
the first part will be executed when the loop starts
for the first time
the second part ("i < high") is the condition
for it to loop over again.
the third part will be executen every time the code
block in the loop is closed.
*/
for(let i = low; i < high; i++) {
// the variable i is the index, which is
// the amount of times the loop has looped already
console.log(i);
console.log(array[i]);
} // i will be incremented when this is hit.
// output:
/*
0
foo
1
bar

For Loop
A for loop is a repetition control structure that allows you to efficiently write a loop that needs to be executed a specific number of times.
A for loop is useful when you know how many times a task is to be repeated.
Syntax :
for(initialization; Boolean_expression; update) {
// Statements
}
This is how it works :
The initialization step is executed first, and only once. This step allows you to declare and initialize any loop control variables and this step ends with a semi colon (;).
Next, the Boolean expression is evaluated. If it is true, the body of the loop is executed. If it is false, the body of the loop will not be executed and control jumps to the next statement past the for loop.
After the body of the for loop gets executed, the control jumps back up to the update statement. This statement allows you to update any loop control variables. This statement can be left blank with a semicolon at the end.
The Boolean expression is now evaluated again. If it is true, the loop executes and the process repeats (body of loop, then update step, then Boolean expression). After the Boolean expression is false, the for loop terminates.

# example of forloop and return through factorial
def fact(m):# function factorial
a=1
for e in range(1,m+1):#we will be using for loop
a*=e
return a#return function
x= 5 # put the value in x eg, 5
d=fact(x)
print(d)
output:
120==5*4*3*2*1
