How Can I Create Dynamic Variable Names Within Loops in Python?

Dynamic Variable Naming with Loops

In Python, loop variables are typically named using a simple incrementing counter (e.g., for x in range(10)). However, situations arise where you may need to create custom variable names within a loop.

One approach is to use dictionary literals, as illustrated in the following example:

d = {}
for x in range(1, 10):
    d[f"string{x}"] = "Hello"

This code creates a dictionary where the keys are dynamically generated as strings within the loop ("string1", "string2", etc.) and the values are all set to "Hello." This allows you to retrieve the values later using the variable names stored as keys in the dictionary.

>>> d["string5"]
'Hello'
>>> d
{'string1': 'Hello', 'string2': 'Hello', 'string3': 'Hello', 'string4': 'Hello', 'string5': 'Hello', 'string6': 'Hello', 'string7': 'Hello', 'string8': 'Hello', 'string9': 'Hello'}

While using a dictionary is an effective solution for dynamic variable naming, it is important to note that dictionaries provide key-value associations rather than true variable names. Nevertheless, this approach provides a convenient and flexible way to store and retrieve data with dynamically generated variable names.
