Python for Absolute Beginnerロードブロッキング;第5章、チャレンジ＃2 - 無効な構文

Question

私はプログラミングが初めてです。私は1ヵ月ほど前から真剣に勉強し始めました。

私が読んできた本は、絶対初心者のためのPythonであり、私は第5章のチャレンジセクションの不調を打ちました。私はこの本を一定のペースで進めてきましたが、以前は1つの課題にしか失敗していませんでした。この新しいものは私に「無効な構文」のエラーを与えています。なぜそれがわかりません。

私の（確かに経験の浅い）心にはすべてが整然としているようです。 私は間違ったことを理解できません。ここで

コードです：

#Character Creator 

#Establish defualt stats 
ws = 10 
st = 10 
dx = 10 
ht = 10 
points = 30 

#Tell the user about the program 
print(
    """ 
Welcome to the character creator. Here you will allocate a pool of 30 
points between 4 different stats: Strength, Dexterity, Health, and Wisdom. 
You may also decrease any of these stats to gain extra points. 
The game is over when your point pool is empty. 
    """) 

#Set the selection process to continue until the user has spent their points 
while points > 0:

私はそれはおそらく非常に洗練知っているが、これは私が私の限られた経験で行うことができる最高でした。

while spent_points > points: 

エラーは「無効な構文」と表示されます。私はそれが何を意味しているのか、私が間違っていたのか分かりません。強調表示されたテキストは「while」部分のみでした。私はその固定されたものとその行の最後に "："文字でエラーが現れたかどうかを見るために "while"を "if"に変更しようとしましたが、メッセージは同じでした。

私はこのサイト上の他の場所で見て、それよりも、より具体的な強調表示されたテキスト前に、問題のこのことについて何か証拠が、何を読みました。

ご協力いただきまして大変感謝します。

Answer 1

は、あなたはそれ以上の次の行で構文エラーがあります。これはあなたがパターンint型（入力を（持っているすべての時間に発生していること

spent_points = int(input("How many points will you spend?: ")) 

ノートへ

spent_points = int(input("How many points will you spend?: ") 

変更これを..すべてのケースに余分な括弧を追加してください。

さらに、一度あなたがあなたのif_startでIndentionErrorを実行すると、 at == "2"：ステートメント。 "if"ステートメントの前に隠されたスペースがあるように見えます。エラーを取り除くために、それぞれの前に1回バックスペースします。
