Sure you can; it's called a dictionary:
d = {}
for x in range(1, 10):
d["string{0}".format(x)] = "Hello"
>>> d["string5"]
'Hello'
>>> d
{'string1': 'Hello',
'string2': 'Hello',
'string3': 'Hello',
'string4': 'Hello',
'string5': 'Hello',
'string6': 'Hello',
'string7': 'Hello',
'string8': 'Hello',
'string9': 'Hello'}
I said this somewhat tongue in check, but really the best way to associate one value with another value is a dictionary. That is what it was designed for!

It is really bad idea, but...
for x in range(0, 9):
globals()['string%s' % x] = 'Hello'
and then for example:
print(string3)
will give you:
Hello
However this is bad practice. You should use dictionaries or lists instead, as others propose. Unless, of course, you really wanted to know how to do it, but did not want to use it.

r/learnpython on Reddit: Trying to create a loop to create dynamic variables
January 23, 2022 -
Hi, I think I understand how to do this high level, but was hoping for help that was a little more specific.
From my understanding, creating dynamic variables goes like this:
for i in range(0, 9):
globals()[f"my_variable{i}"] = f"Hello from variable number {i}!
However, what if I want to make a variable that says server1, server2...server9- how do i attach the word to the beginning?
Top answer 1 of 4

globals()[f"server{i}"] Don't do that though. Use a dictionary, or a list.

Well, I'd say DON'T DO THAT - use a dict instead, or a list named_stuff = {} # empty dictionary for i in range(0, 9): named_stuff[f"my_variable{i}"] = f"Hello from variable number {i}!" print(named_stuff) # just to illustrate they were created
Dynamic variable name
Suppose i have to set q_variable = 0 a_variable = 0 def stats(choice): choice + '_variable' += 1 stats('q') Here after adding the choice + ‘_variable’ will become string. If i want to change the q_variable or the a_variable depending on the choice we provide to the function. How do we do that? More on discuss.python.org

Python Loop for Dynamic Variable Names: How to Create double_1, double_2...double_12 — CyberAngles.org
You can modify these dictionaries to create dynamic variables in the global or local scope. Warning: This method is not recommended because it pollutes the namespace and can accidentally overwrite existing variables. globals() returns a dictionary of the current global namespace. By adding a key-value pair to this dictionary, you create a global variable. # Loop from 1 to 12 to create global variables for i in range(1, 13): # Generate the variable name (e.g., "double_3") var_name = f"double_{i}" # Assign the value (2 * i) to the global variable globals()[var_name] = 2 * i # Access the variables like regular global variables print(double_7) # Output: 14 print(double_12) # Output: 24

Answer (1 of 6): You don’t. Now I know someone will come along with a solution involving locals(), but then to use those ‘variables’ in your code you would need use ‘locals()’. Misusing locals() especially writing to it is a sign of a bad design. It is far simpler just to add items to a diction...

Unless there is an overwhelming need to create a mess of variable names, I would just use a dictionary, where you can dynamically create the key names and associate a value to each.
a = {}
k = 0
while k < 10:
# dynamically create key
key = ...
# calculate value
value = ...
a[key] = value
k += 1
There are also some interesting data structures in the collections module that might be applicable.

globals() returns a dictionary of the module's variables. You can create a new variable by creating a key on that dictionary:
# By default, a module has some hidden variables defined
print({k: v for k, v in globals().items() if not k.startswith("__")})
for i in range(1, 11):
globals()[f"my_variable_{i}"] = i
print()
print(my_variable_1)
print(my_variable_2)
# and so on
print()
print({k: v for k, v in globals().items() if not k.startswith("__")})
Result:
{}

Top 8 Methods to Dynamically Create Variable Names in Python Loops
November 6, 2024 - While creating variable names dynamically via globals() is feasible, it is considered bad practice. This approach involves modifying the global namespace, which can lead to unintended issues. for x in range(0, 9): globals()['string%s' % x] = 'Hello' print(string3) # Output: Hello · The exec() function allows you to execute dynamically created Python statements, but like globals(), it carries risks and makes your code harder to follow.
