python中变量名和字符串的相互转换

字符串作为变量名

可以使用locals()，globals()，vars()进行转换。
代码示例：

ls = ['A', 'B', 'C']
for i in ls:
    globals()[i] = [1,2,3]
    
print(A,B,C)

输出为：
[1, 2, 3] [1, 2, 3] [1, 2, 3]

变量名作为字符串

代码示例：

import inspect
def retrieve_name(var):
    callers_local_vars = inspect.currentframe().f_back.f_locals.items()
    return [var_name for var_name, var_val in callers_local_vars if var_val is var]

A, B, C = [1, 2, 3], [4, 5, 6], [7, 8, 9]
ls = [A, B, C]
for i in ls:
    i1 = retrieve_name(i)[0]
    print('%s ='%i1, i)

输出为：
A = [1, 2, 3]
B = [4, 5, 6]
C = [7, 8, 9]
