## Mastery19 – While loop

the while loop will go on until the condition to break it is met and can run undefinedly.

to use it write while and the condition>

while x < 50:

do something

## Mastery18 – Nesting of conditional statements

nesting is when you put conditionals inside other ones to check another condition.

if something:

thing1

if something2:

this

else:

that

there is an if and else conditionals inside the initial if.

## Mastery17 – Conditional elif

the elif conditional es a combination of the else and if conditionals, it needs a to fulfill a conition like the if conditional but it will be ignored if the condition above is fulfilled like an else conditional.

if x != 0:

print(“it’s not a 0”)

if x > 0:

print(“more than 0”)

if x < 100:

print(“less than 100”)

and we used 50 as x, the program will print everything since 50 meets each condition but if we change any of the if conditionals after the first to elif the program would ignore them since the first will be true. elif is to stick two statements as one.

## Mastery16 – Conditional else

the else conditional goes after an if conditional, when none of the conditionals above is fulfilled then the else conditon is used. for example:

x = 5

if x < 5:

if x > 5:

else:

print (“it’s a 5”)

the rpogram wil ignore the other conditionals since 5 is not lower or higher than 5 and will use the else.

## Mastery15 – Conditional If

the conditional if es used whe you want something to happen only when a a certain condition is met. like comparing two variables and if they are equal the the program will follow the contition.

x = input()

y = input()

if x == y:

print (“it is the same”)

## Mastery14 – Creating a python module

creating a module is no different from a normal program, create a python file and create a few functions in it.

file name: mymodule.py

def function1():

print (“function 1”)

# end of the module.

and in another program import it an call the function:

import mymodule.py

mymodule.function1()
