How to shuffle and print a list of emoji using python?

I want to generate emojis in a random way. I tried two different methods but still not habing an output mixed

import random

soleillever ="\U0001f305"
Soleildodo = "\U0001f634"
nuage = '\u2601'
soleilnuage = "\U0001f326"
nuageeclair = "\U0001f329"
rainbow = '\U0001f308'
termo = '\U0001F321'
soleil = '\U0001f31e'
soleil2 = "\U0001f31d"
nuageeclairpluie = "\u26C8"
flocon = "\u2744"
print(soleil,soleil2,termo,rainbow,nuageeclair,soleilnuage,nuage,flocon)


a =[rainbow + nuageeclair + soleilnuage + nuage + soleil2 + nuageeclairpluie + flocon + rainbow]
b = random.sample(a, k=len(a))
print(b)


a1 = [rainbow + nuageeclair + soleilnuage + nuage + soleil2 + nuageeclairpluie + flocon + rainbow]
b1 = random.shuffle(a1)
print(b1)

Here is the output with the type

['🌈🌩🌦☁🌝⛈❄🌈']
 Here is b <class 'list'>

B1 gives me None
Here is b1<class 'NoneType'>

If someone have an advice, I will appreciate ! B.

There appear to be two mistakes in your code. The first is that random.shuffle applies the shuffling in-place.

As per my comments, random.shuffle does not return anything. As such, when you assigned b1 to the value returned by random.shuffle, it is set to nothing, i.e. None You can imagine the function as looking like this:

def shuffle(input):
   # do something to input

instead of

def shuffle(input):
   # do something to input
   return input

In your case, it should work if you do the following.

# normal, un-shuffled list
print(a1)
random.shuffle(a1)
print(a1) # same array, but now it has been shuffled

The second problem is that you create a1, as list of strings by using the + operation. As a result, this essentially creates a single string, contained within a list instead of a list of strings. The difference is as a follows:

lst0 = ['hello'] 
random.shuffle(lst0) # returns ['hello']

lst1 = ['h'+'e'+'l'+'l'+'o'] # this is identical to lst0
random.shuffle(lst1) # returns ['hello']

lst2 = ['h','e','l','l','o']
random.shuffle(lst2) # returns ['o', 'h', 'l', 'e', 'l']

In your case, try to use commas instead of +. That is:

a1 = [rainbow , nuageeclair , soleilnuage , nuage , soleil2 , nuageeclairpluie , flocon , rainbow]

or directly

a1 = ["\U0001f305","\U0001f634",'\u2601',"\U0001f326","\U0001f329",'\U0001f308','\U0001F321','\U0001f31e',"\U0001f31d","\u26C8","\u2744"]
