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

Creating Dynamic Variable Names within Loops

When iterating through a loop, it's often necessary to create unique variables. However, creating individual variable names can be cumbersome.

For instance, let's consider the following example:

for x in range(0,9):
    string'x' = "Hello"

In this case, all the variables (string1, string2, ...) will be assigned the same value ("Hello").

Solution: Using Dictionaries

To create dynamic variable names with different values, you can utilize dictionaries:

d = {}
for x in range(1, 10):
    d["string{0}".format(x)] = "Hello"

This code creates a dictionary where the keys are dynamically generated strings (e.g., "string1", "string2"). Each key is associated with the value "Hello".

Accessing Variables

To access the individual variables, use the key within square brackets:

d["string5"]  # Outputs 'Hello'

Therefore, dictionaries provide a convenient and efficient way to dynamically create and manage variables within loops, associating each variable with a unique value.
