How Can I Avoid Overwriting Variables When Using Numerical Suffixes in Loops?

Variable Naming in Loops: Beyond Numerical Suffixes

When iterating through loops, it's common to use numerical suffixes to create unique variable names. However, in the following code:

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

Using this approach, all the variables (string1, string2,...) will end up holding the same value ("Hello"). How can you create distinct variable names that retain their intended meaning?

Utilizing Dictionaries

The solution lies in using dictionaries, which are efficient structures for associating one value with another:

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

In this code:

  • The dictionary d is constructed.
  • Each iteration of the loop creates a unique key within the dictionary using string concatenation (e.g., "string5").
  • The value assigned to each key is "Hello."

Accessing the value associated with a specific key is straightforward:

d["string5"]  # outputs 'Hello'
Copy after login

By using dictionaries, you can easily create variables with unique names while still maintaining the semantic connection between the key and the associated value.
