Python Solutions
Solution 1 - Python
x='buffalo'
exec("%s = %d" % (x,2))
After that you can check it by:
print buffalo
As an output you will see:
2
Solution 2 - Python
This is the best way, I know of to create dynamic variables in python.
my_dict = {}
x = "Buffalo"
my_dict[x] = 4
I found a similar, but not the same question here https://stackoverflow.com/questions/11354214/creating-dynamically-named-variables-from-user-input
Solution 3 - Python
You can use a Dictionary to keep track of the keys and values.
For instance...
dictOfStuff = {} ##Make a Dictionary
x = "Buffalo" ##OR it can equal the input of something, up to you.
dictOfStuff[x] = 4 ##Get the dict spot that has the same key ("name") as what X is equal to. In this case "Buffalo". and set it to 4. Or you can set it to what ever you like
print(dictOfStuff[x]) ##print out the value of the spot in the dict that same key ("name") as the dictionary.
A dictionary is very similar to a real life dictionary. You have a word and you have a definition. You can look up the word and get the definition. So in this case, you have the word "Buffalo" and it's definition is 4. It can work with any other word and definition. Just make sure you put them into the dictionary first.
