import factorial

After importing the function, we can call the function factorial in the following way:

import factorial

print(factorial.compute_factorial(5))
print(n)

Here, the function factorial.compute_factorial() indicates the compute_factorial() function within the file factorial.py. The output of the above program will be:

120

Please note that we can also use the “from import ” statement to import only the compute_factorial() function from the file factorial.py. In that case, the function can be used in the following way:

from factorial import compute_factorial

print(compute_factorial(5))

We can also import a module using the statement “import as ” in the following way:

import factorial as fact

print(fact.compute_factorial(5))

Here, the factorial module will be imported and the module will be available in the program as fact. So, we will need to use fact.compute_factorial() to call the function.

Similarly, we can also import a function or value from a module in the following way:

from factorial import compute_factorial as compute_fact

print(compute_fact(5))

Here, the compute_factorial() function will be imported in the new program and will be available as compute_fact() function. So, print(compute_fact(5)) will print the following output:

120
