Multiple loop print without redundancy

Question

I want to inter-loop print, I don't know if that is even a word but let me demonstrate with the code bellow

def primer():
    print (greet(), "\n", intro(), "\n" ,origi())

def greet():
    return("Hola ")

def intro():
    return("Mi nombre es Leon ")

def origi():
    return("I am from Guadalajara")

primer()

the output is:

Hola  
 Mi nombre es Leon  
 I am from Guadalajara

Desired output.

Hola



Hola
 Mi nombre es Leon



Hola
 Mi nombre es Leon
 I am from Guadalajara

That would be to pirint

greet

greet
intro

greet
intro
origi

Without all the redundancy or as little as possible.

Could you describe more or less how your desired output is related to your function definitions? It is a bit complicated to guess. — Hyperboreus, Oct 21 '13 at 00:11

There really is no need for a loop in your program, just spell out the function calls.

If you by all means want a loop, you can use something like this although it is highly senseless:

def primer():
    for s in ([greet(), intro(), origi()][:i + 1] for i in range(3)):
        print('\n'.join (s) + '\n')

With the minimum of alteration to your code, you can do what you want by printing the previous function's return value when the next is called:

def primer():
    print (greet(), "\n", intro(), "\n" ,origi())

def greet():
    return("Hola ")

def intro():
    print(greet())
    return("Mi nombre es Leon ")

def origi():
    print(intro())
    return("I am from Guadalajara")

primer()

Gives me:

>>> 
Hola 
Hola 
Mi nombre es Leon 
Hola  
 Mi nombre es Leon  
 I am from Guadalajara

This should work for any arbitrary list of functions (printers) that return strings:

def primer():
    printers = (greet, intro, origi)
    print('\n\n\n\n'.join(['\n'.join([printer() for printer in printers[1:n]]) for n in range(len(printers)+1)]))

OUTPUT:

Hola 



Hola 
Mi nombre es Leon 



Hola 
Mi nombre es Leon 
I am from Guadalajara
