我想用嵌套字典中的空字符串替换 None 。
test={
"order":1234,
"status":"delivered",
"items":[
{
"name":"sample1",
"code":"ASU123",
"unit":None
} ],
"product":{"name":None,"code":None}
}
我想用空字符串替换 None 并将字典的转换存储到另一个变量(如 test1)中。
以下代码不允许我将其存储在另一个变量中。
def replace_none(test_dict):
# checking for dictionary and replacing if None
if isinstance(test_dict, dict):
for key in test_dict:
if test_dict[key] is None:
test_dict[key] = ''
else:
replace_none(test_dict[key])
# checking for list, and testing for each value
elif isinstance(test_dict, list):
for val in test_dict:
replace_none(val)
