Mastery18 - Nesting of conditional statements

1 min read

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

1 min read

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 we had this conditionals:

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

1 min read

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 use else since none of the conditions above was fulfilled.

 

Mastery15 - Conditional If

1 min read

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

1 min read

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()
