Is there a way to link several if statements in Python so that they all run simultaneously?

I need to write a program that replaces characters in a string, I need to do it without using replace(). This is not a problem as translate() works just fine. However, I need to replace multiple characters and right now, I can only replace one at a time, as in only one of the 'if' statements runs. It looks somewhat like this:

#constants
X = 'xex' 
Z = 'zaz'
    
#then the user provides a string using input() 

def newest_string():

    for i in string:

        if i == 'x':
            new_word = word.translate({ord(i): X for i in 'x'})
            continue
        elif i == 'z':
            new_word = word.translate({ord(i): Z for i in 'z'})
            continue

         #then there are many more similar statements using translate() because 
           there are many characters that need to be changed

        else:
             continue

    return string

Note that str.translate converts all occurrences of the specified characters, so the for loop is just a waste of efficiency.

Also, {ord(i): X for i in 'x'} and {ord(i): Z for i in 'z'} are the exact equivalent of {ord('x'): X} and {ord('z'): X}, as there is only one character both 'x' and 'z'.

Here is how you can use a dict() with more than one conversion:

#constants
X = 'xex' 
Z = 'zaz'
    
#then the user provides a string using input() 
def newest_string(word):
    new_word = word.translate({ord('x'): X, ord('z'): Z})
    return new_word

print(newest_string('I am at the zoo. So exciting!'))

Output:

I am at the zazoo. So exexciting!
