Answer 1

Answer:

Pythonmodules can be renamed when importing

Answer 2

Answer:

Explanation:

Modules

If you quit from the Python interpreter and enter it again, the definitions you have made (functions and variables) are lost. Therefore, if you want to write a somewhat longer program, you are better off using a text editor to prepare the input for the interpreter and running it with that file as input instead. This is known as creating a script. As your program gets longer, you may want to split it into several files for easier maintenance. You may also want to use a handy function that you’ve written in several programs without copying its definition into each program.

To support this, Python has a way to put definitions in a file and use them in a script or in an interactive instance of the interpreter. Such a file is called a module; definitions from a module can be imported into other modules or into the main module (the collection of variables that you have access to in a script executed at the top level and in calculator mode).

A module is a file containing Python definitions and statements. The file name is the module name with the suffix .py appended. Within a module, the module’s name (as a string) is available as the value of the global variable __name__. For instance, use your favorite text editor to create a file called fibo.py in the current directory with the following contents:

# Fibonacci numbers module

def fib(n): # write Fibonacci series up to n

a, b = 0, 1

while b < n:

print(b, end=' ')

a, b = b, a+b

print()

def fib2(n): # return Fibonacci series up to n

result = []

a, b = 0, 1

while b < n:

result.append(b)

a, b = b, a+b

return result

Now enter the Python interpreter and import this module with the following command:

>>>

>>> import fibo

This does not enter the names of the functions defined in fibo directly in the current symbol table; it only enters the module name fibo there. Using the module name you can accept.

Therefore it is b
