如何在Python中动态创建变量的名称? [英] How can I dynamically create a name of a variable in Python?

问题描述

我在python中有一个函数

I am having a function in python

def func(dataFrame,country,sex):
    varible_name=dataFrame[(dataFrame['land']==country) & (dataFrame['sex']==sex)]

现在，例如，我调用此函数

Now, for example, I call this function

func(dataFrame,'England','M')

我希望变量名是England_M而不是variable_name.

I want that variable name be England_M instead of variable_name.

推荐答案

您无法在Python中做到这一点. 相反，您可以做的是将结果存储在例如键= England_M的字典下.

You can't do that in Python. What you can do instead is store the results under a dictionary with key = England_M for instance.

根据您的情况，您可以执行以下操作:

In your case, you could do the following :

def func(dataFrame,country,sex):
    tmp = dataFrame[(dataFrame['land']==country) & (dataFrame['sex']==sex)]
    variable_name = "{c}_{s}".format(c=country, s=sex)
    return dict(variable_name=tmp)

现在使用它:

results = func(dataFrame, "England", "M")
print(results['England_M'])
