This is the best way, I know of to create dynamic variables in python.
这是最好的方法，我知道在 python 中创建动态变量。
my_dict = {}
x = "Buffalo"
my_dict[x] = 4
I found a similar, but not the same question here Creating dynamically named variables from user input
我在这里发现了一个类似但不一样的问题 从用户输入创建动态命名的变量

You can use a Dictionary to keep track of the keys and values.
您可以使用字典来跟踪键和值。
For instance...
例如...
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.
字典与现实生活中的字典非常相似。你有一个词，你有一个定义。您可以查找单词并获得定义。所以在这种情况下，你有“Buffalo”这个词，它的定义是 4。它可以与任何其他词和定义一起使用。只要确保你先把它们放进字典里。
