Dynamically Creating u-strings in Python

Question

https://docs.python.org/2/tutorial/introduction.html#unicode-strings

I'm currently trying to figure out how to dynamically create u-strings (which are in the form of u'helloWorld' for example). I'd like to create a u-string with string concatenation or string injection if it were possible, to use a variable to dynamically create a new u-string such as u'{variableName}'. Is there a way to accomplish this?

The usage of the Python 2 u-strings are for usage of the gcloud functions, where I'm trying to dynamically add documents. The documentation makes use of u-strings and can be found at:

https://firebase.google.com/docs/firestore/manage-data/add-data

Strings vs. unicode strings only makes sense in Python 2, and Python 2 seldom makes sense in 2021. What are you trying to accomplish? (In fairness, Apple has muddied the waters by making Python 2 their default for way too long). — John Coleman

Are you actually using Python 2? In Python 3, all strings are Unicode. They're managed just like regular strings. — Tim Roberts

What have you tried that isn't working? mys = u"one" + u"two" should work fine in Python 2. — Tim Roberts

Python 2 reached its end of life on January 1, 2020. And all strings are u-strings by default in Python 3 if I'm not wrong. — accdias

u-strings don't exist anymore in Python 3. They are the same as normal strings. So just use normal strings.

# Python 3
>>> u'Hello'
'Hello'

Do not use Python 2 as it is no longer supported. If you insist on using Python 2, try:

# Python 2
>>> unicode('Hello')
u'Hello'

It's for use in gcloud functions (firebase.google.com/docs/firestore/manage-data/add-data), I don't have another way around it.

@cloudxleaf OK, it is just a weird way to write normal strings then. Just use a normal string.
