Question

でハッシュにアクセスするとき、私は私の最初のPythonプロジェクトをやっていると私は次のコードを持っている：私はこのエラーを取得しています

response = urlopen(request) 
    flights = response.read() 

    text_file = open("Output.txt", "w") 
    text_file.write(flights) 
    text_file.close() 

    minPrice = LARGE_CONSTANT 
    for flight in flights["Quotes"] 
     if(flight["MinPrice"] < minPrice) 
     minPrice = flight["MinPrice"] 

を：

for flight in flights["Quotes"] 

           ^
SyntaxError: invalid syntax 

は、これは非常に基本的な問題のように思えますしかし、私は何が間違っているのか理解できません。 ハッシュflightsには、以下の内容があります。

なぜ私はこのようなflights["Quotes"]ハッシュにアクセスすることはできませんか？

Answer 1

最後に:が欠けています。

response = urlopen(request) 
flights = response.read() 

text_file = open("Output.txt", "w") 
text_file.write(flights) 
text_file.close() 

minPrice = LARGE_CONSTANT 
for flight in flights["Quotes"]: 
    if(flight["MinPrice"] < minPrice): 
     minPrice = flight["MinPrice"] 

ちょっとシンプル、申し訳ありませんが私はより有用であることはできません。
すべてのpythonブロック（for、if、while、with）は、開始行の最後に:が必要で、そのコードブロックに属するコードにインデントがあります。この場合はfor ...:であり、うまくいえばif ...:です

も（それが4つのスペースやコードのブロックごとにタブでなければなりません）
