How to create dynamic variable name in Python
By Yashkumar PatelA dynamic variable name, sometimes called a variable, is a variable with a name that is the estimation of another variable.
Despite the fact that Python is a very dynamic language in which nearly everything is an object, it is possible to construct dynamic variables in Python.
In Python, how do you make a dynamic variable name?
This lesson will go through many techniques for naming a dynamic variable in Python.
There are many ways of it, Let’s see the first step
1. Create a Dynamic Variable Name in Python Using for Loop
Iteration may be used to create a dynamic variable name in Python.
This approach will also use the globals() function in addition to the for loop.
Python’s globals() function returns a dictionary containing the current global symbol table.
In Python, the for loop and the globals() function are used to construct a dynamic variable name.
Let’s learn through an Example,
for x in range(0, 7):
globals()[f"variable1{x}"] = f"Hello CodeSpeedy Student {x}!!!"
print(variable12)Output:
Hello CodeSpeedy Student 2!!!
2. Create a Dynamic Variable Name in Python Using a Dictionary
Dictionaries have both a key and a value, it’s simple to construct a dynamic variable name using them.
In Python, the following code creates a dynamic variable name using a dictionary.
var = "CodeSpeedy"
val = 1
dict1 = {var: val}
print(dict1["CodeSpeedy"])Output:
1
However, it is possible to define a dynamic variable name in Python, it is pointless and unneeded because Python data is produced dynamically. The objects in Python are referred to throughout the code. If the item’s reference exists, the object itself exists.
thanks for helping out, but i am stuck in how to call them dynamically like in the first method we used print(variable12), however if i want want to print variable1x (may be i want to use variable15 or 17) dynamically depending on some condition, how can i do that
Correct Shurjeel
2nd method is wrong as it is just a static concept.
My example:
# Create an empty dictionary to store dynamic variables
dynamic_variables = {}
# Use a for loop to create dynamic variable names and assign values
for x in range(0, 7):
variable_name = f”variable1{x}”
variable_value = f”Hello CodeSpeedy Student {x}!!!”
dynamic_variables[variable_name] = variable_value
# Access and print the value of a dynamic variable
print(dynamic_variables[“variable12”]) # Output: Hello CodeSpeedy Student 2!!!
Here I have used a dictionary and for loop to create a dynamic variable name in my example.
