How to create a variable with a name containing another variable in python?

Question

I have defined a variable as below:

time = "0915"

now next I want to create another variable naming it as follows:

x_0915 = "some value" #### idea is to have previously defined variable value in this new variable name itself

how do I make it automatic as I will be having this kind of multiple situations?

so the task is I want to concatenate "x" with the previously defined variable value and use it as a name for the new variable.

You shouldn't do this. Use a *container*, like a `list` or a `dict` — juanpa.arrivillaga, Jun 26 '22 at 07:27
How would use `x_0915` if it depends of the value of `time` ? — azro, Jun 26 '22 at 07:29

Use a dictionary instead of defining dynamic variables and creating a mess.

time = ["0915", "0920", "0925"]
a = {}
for i in time:
    a[f"x{i}"] = "some value"

print(a)

Output

{'x0915': 'some value', 'x0920': 'some value', 'x0925': 'some value'}

Please paste text, not image of it – azro Jun 26 '22 at 07:35
@azro I changed it, But is there any reason for the text? because image is also clear – Sidharth Mudgil Jun 26 '22 at 07:37
Text is as clear as image, responsive on different device, copyable, doesn't request to load, it, will always be accessible. And why put an image a text :) – azro Jun 26 '22 at 07:41
I can't paste an image into my IDE and get python to run the code. – quamrana Jun 26 '22 at 07:42
Dictionary comprehensions can clean this up a bit: `a = {f"x{i}": "some value" for i in time}` – Chris Jun 26 '22 at 07:47
