Question

如何将dictdict = [{'a':'1','b':'2','c':'3'},{'a':'1','b':'2','c':'3'}]转换转换成_dict？_dict = {'a':['1','1'], 'b':['2','2'], 'c':['3','3']}**

Answer 1

cc = {}
dict = [{'a':'1','b':'2','c':'3'},{'a':'1','b':'2','c':'3'}]
for i in dict:

for k, v in i.items():    if k not in cc:
        cc[k] = [v]    else:
        cc[k].append(v)

print(cc)
