How to get the variable name as string from an array of variables?

I have array of dataframes:

a=[df1,df2,df3]

But I need the variable name as a string

b=['df1','df2','df3']

How can I do this?

>Solution :

Tooking inspiration from this answer,
you can solve your problem with the following code:

def get_var_name(variable):
     for name in globals():
        if eval(name) is variable:
            return name

a = [df1, df2, df3]

b = [get_var_name(el) for el in a]
# print(b) gives ['df1', 'df2', 'df3']
