python从函数返回字典

Question

我尝试了很多但是仍然有从函数返回字典的问题。我可以从函数内部打印d1和d2但不在外面打印。当我使用以下脚本时，我得到：NameError：name＆＃39; d1＆＃39;没有定义。谢谢您的帮助！

ref = """text a"""

target = """text b"""

def text_to_dict(x):
    # value formatting to list = new_values
    # key formatting to list = keys
    # dict creation from keys and new_values
    if x == ref:
        d1 = dict(zip(keys, new_values))
        return d1
    elif x == target:
        d2 = dict(zip(keys, new_values))
        return d2

text_to_dict(ref)

text_to_dict(target)

print(d1)

print(d2)

Answer 1

d1和d2是函数变量，它们在函数外部不可见。

dict1 = text_to_dict(ref)

dict2 = text_to_dict(target)

print(dict1)

print(dict2)
