Dictionaries in dictionaries

[misha]

It looks raw

fin = open('input.txt', 'r', encoding='utf8')
fout = open('output.txt', 'w', encoding='utf8')
data = list(map(lambda x: x.split(), fin.readlines()))
myDict = {}

for i in data:
    myDict[i[0]] = {i[1]: int(i[2])}

print(myDict, file=fout)

I know that my innerdictionary gets rewritten everyt time there is a new value in the loop. So, that's what I get in the end:

{'Smith': {'Apple': 10}, 'Davis': {'Apple': 30}, 'Brown': {'Potato': 50}, 'Miller': {'Cucumber': 40}}
