How to put random characters in between random strings at any position?

Question

I have two lists that are generated automatically in Python (using String and Random). Say I ran the code and currently have them like this:

random_word = ['Sirius','July','Seven']
random_char = ['#','$','%']

The desired output is something like this:

random_list = ['Siriu$s', 'J%uly', 'S#even']

Note 1: The special characters can be positioned either all at the same position or at any random position

Now, this is the part where I’ve stopped, because I haven’t found a way yet to –at least– put the special characters at any specific position in each string of the list random_word:

for k in random_words:
  for i,j in list(enumerate(random_char)):
    random_list = k.insert(i*2, j)
print(random_list)

Note 2: I know my mistake above, k is a str and can’t use the insert() (that’s the main error I know for now :P). However, I wanted to show my thought of the process of what I initially was attempting to do; putting a random character j from random_char at the second position i*2 of the random word without replacing it, using two for loops

As always any guidance on how to make this right is very well appreciated! 🙂

Answer 1

IIUC, one way using random.randrange with random.shuffle:

random_word = ['Sirius','July','Seven']
random_char = ['#','$','%']

random.shuffle(random_char)
for w, c in zip(random_word, random_char):
    i = random.randrange(0, len(w)+1)
    print(w[:i] + c + w[i:])

Possible output (since it’s random):

S#irius
%July
S$even
