Hope that helps Using the replace method is much simpler than how you are attempting to use it.
code :
phrase=input('please enter a phrase    ')

copy = phrase.replace('e', 'x')
copy = copy.replace(' ', '*')
print(copy)

Does that help How to replace characters in a string which we know the exact indexes in python?
code :
name = "ABCDEFGH"
nameL = list(name)

for i in range(len(nameL)):
    if i%2==1:
        nameL[i] = '$'

name = ''.join(nameL)
print(name)

I hope this helps . That's easy, just define a dictionary which maps characters to their replacement.
code :
>>> replacers = {'A':'Z', 'T':'U', 'H':'F'}
>>> inp = raw_input()
A T H X
>>> ''.join(replacers.get(c, c) for c in inp)
'Z U F X'
>>> [replacers.get(c, c) for c in inp]
['Z', ' ', 'U', ' ', 'F', ' ', 'X']
>>> 'x'.join(['a', 'b', 'c'])
'axbxc'

hope this fix your issue I have a python script that was written originally for Python 2, that I've had to change for Python 3. , It would appear that
code :
fileinput.input(file, inplace=True)
with open(file, 'r', encoding='utf8') as f:
import fileinput
import datetime
import sys
import re
import os
year = str(datetime.datetime.now().year)
assemblyInfoPattern = re.compile(r"^\[assembly:\sAssemblyCopyright\(\"Copyright.*\]$")

for root, dirs, files in os.walk('.') :
    for file in files :
        if file == 'AssemblyInfo.cs' :
            print (f'Checking {root}\\AssemblyInfo.cs')
            outputFile = ""
            with open(os.path.join(root, file), 'r', encoding='utf8') as f:
                for line in f.readlines() :
                    replacementString = '[assembly: AssemblyCopyright("Copyright © 2014-' + year + '")]'
                    outputLine = assemblyInfoPattern.sub(replacementString, line)
                    outputFile = outputFile + outputLine
            with open(os.path.join(root, file), 'w', encoding='utf8') as f:
                f.write(outputFile)
[assembly: AssemblyCopyright("Copyright © 2014-2019")]

wish help you to fix your issue Turns out the problem is not that I am feeding non-UTF-8 characters to MySQL, but that I am feeding four-byte UTF-8 characters to MySQL when it supports only three-(and fewer)byte UTF-8 characters (according to this documentation)
This solution retains all the supported UTF-8 characters, and converts the unsupported UTF-8 characters to '?':
