I know that the regular input function can accept single lines, but as soon as you try to write a string paragraph and hit enter for the next line, it terminates. Is there a beginner-friendly way to accept multiline user string inputs as variables?

A common way of doing this in programs is to have an "I'm done" string (e.g. a single period), and to keep reading in lines until the line read matches that string.
print("Enter as many lines of text as you want.")
print("When you're done, enter a single period on a line by itself.")
buffer = []
while True:
print("> ", end="")
line = input()
if line == ".":
break
buffer.append(line)
multiline_string = "\n".join(buffer)
print("You entered...")
print()
print(multiline_string)

You can do that using sys library
import sys
x = sys.stdin.read()
Comments
def processString(x):
print(x.replace('process','whatever'))
lines = ""
while True:
if lines == "":
lines = ""
print("Enter string:")
x = input()
if x == "" and lines != "":
processString(lines)
break
else:
lines += x
# then hit enter once after multi-line string to process it
Comments
import sys
s = sys.stdin.read()
# print(s) # It will print everything
for line in s.splitlines(): # to read line by line
print(line)

While this may address the issue, you also want to provide a way to get out of the loop. Otherwise, this will be an endless multiline user input.
[input() for i in range(int(input()))]
for n multiline user inputs, each index in the list will be a new line input from the user.

Line=""
while True:
x=input()
Line=Line+" "+x
if "." in x:
break
print(Line)

Line=Line+" "+x is inefficient in Python, it's better to use join. Also, this would stop as soon as a line contains a dot, which could appear in many situations (Well... 3.14?). Finally, it removes the newlines between the inputs...
