# Find out how to Test for Consider Python

## The problem#

This operate ought to take a look at if the `issue` is an element of `base`.

Return `true` if it’s a issue or `false` if it’s not.

Elements are numbers you possibly can multiply collectively to get one other quantity.

2 and three are components of 6 as a result of: `2 * 3 = 6`

• You will discover an element by dividing numbers. If the rest is 0 then the quantity is an element.
• You should utilize the mod operator (`%`) in most languages to examine for a the rest

Examples:

2 shouldn’t be an element of seven as a result of: `7 % 2 = 1`

Word: `base` is a non-negative quantity, `issue` is a constructive quantity.

Possibility 1:

``````def check_for_factor(base, issue):
return base/issue == int(base/issue)
``````

Possibility 2:

``````def check_for_factor(base, issue):
return base % issue == 0
``````

Possibility 3:

``````check_for_factor=lambda a,b:not apercentb
``````

## Take a look at circumstances to validate our answer#

``````import take a look at

@take a look at.describe("Fastened Checks")
def fixed_tests():
@take a look at.it("Ought to return True")
def should_return_true():
take a look at.assert_equals(check_for_factor(10, 2), True)
take a look at.assert_equals(check_for_factor(63, 7), True)
take a look at.assert_equals(check_for_factor(2450, 5), True)
take a look at.assert_equals(check_for_factor(24612, 3), True)

@take a look at.it("Ought to return False")
def should_return_false():
take a look at.assert_equals(check_for_factor(9, 2), False)
take a look at.assert_equals(check_for_factor(653, 7), False)
take a look at.assert_equals(check_for_factor(2453, 5), False)
take a look at.assert_equals(check_for_factor(24617, 3), False)
