単純な条件の場合の構文エラー（partychoice = Rの場合）

Question

Pythonで作業している新しいプログラマ2.7。

このコードでは、if 'partychoice = R、' = 'が無効な構文であることを示す行に構文エラーが表示されます。どうしてそれが勝ったのですか？変数を割り当てることはできません。

また、他にもたくさんのエラーがあると確信していますが、私はどこかで始める必要があります。

print "Welcome to 'Pass the Bill', where you will take on the role of a professional lobbyist trying to guide a bill through Congress and get it signed into law by the President!" 
start = raw_input(str ('Press Y to continue:')) 
print 'Great, lets get started!' 
partychoice = raw_input (str("Would you like to be a Republican or Democrat? Type 'R' for Republican or 'D' for Democrat.")) 
if partychoice = R: 
    print 'Ah, the Grand old Party of Lincoln and Reagan. Great Choice!' 
    replegchoice = raw_input (str("What type of bill what you like congress to introduce? Restrictions on abortions, lower income taxes, easier access to automatic weapons, private health plans, or stricter immigration laws? (A = abortion restrictions, L = lower taxes, AW = automatic weapons, H = private health plans, S = stricter immigration laws')) 
    if replegchoice = A or a 
      print 'A controversial choice, despite support of most Republicans, you are sure to face opposition from Democrats in Congress!' 
    if replegchoice = L or l 
      print 'A popular idea, Republicans in Congress are sure to support this idea, as will many American voters!' 
    if replegchoice = AW, aw, Aw, or AW 
      print 'Rural, midwest, and small town voters will love this, as will most Republicans in Congress. Democrats and voters in urban cities will surely be less supportive.' 
    if replegchoice = H or h 
      print 'Eimination of Medicare, Medicaid, and Obamacare! Republicans generally like the idea of making each person responsible for paying their own health care costs' 
    if replegchoice = S or s 
      print 'a popular idea supported by president Trump, this is sure face strong opposition from democrats and many voters.' 

ありがとうございました。

Answer 1

あなたは声明で "==" と "=" 交換する必要があります。

if partychoice = R:" 

"=" は代入演算子
ある "==" は等価演算子であります

#assign something to a variable 
x = 5 
print x 
>>5 

#compare for equality 
y = 6 
if y == 6: 
    print y 
else: 
    print "y is not 6" 
>>6

変更

if partychoice == 'R': 

にラインあなたは2 '=' 文字を使用する必要がありますまず。 1つは '='は変数を設定し、2つは等価を比較します。

次に、変数partychoiceと文字列 "R"を比較したいので、引用符が必要です。引用符を付けないと、参照を別のオブジェクトと比較していると考えられます。

Answer 3

の場合=の代入演算子でない比較演算子==を使用する必要があります。

Answer 4

コードにはいくつかの問題があります。

1. あなたが代わりに比較演算子、==の代入演算子、=を使用しています。
2. あなたは現在、あなたの代わりに私がraw_input関数内superfulous str()変換を削除手紙'R'
3. の変数Rとそれらを比較している、文字列を含むと比較するとき'を使用することを覚えておく必要があります。 ""は文字列を定義するため、これは不要です。

4. 文字列の小文字バージョンをチェックするだけで、結果に.lower()関数を呼び出すだけでよいのです。それはあなたに多くの時間を節約します。

   print "Welcome to 'Pass the Bill', where you will take on the role of a professional lobbyist trying to guide a bill through Congress and get it signed into law by the President!" 
   start = raw_input('Press Y to continue:') 
   print 'Great, lets get started!' 
   partychoice = raw_input("Would you like to be a Republican or Democrat? Type 'R' for Republican or 'D' for Democrat.").lower() 
   if partychoice == 'r': 
       print 'Ah, the Grand old Party of Lincoln and Reagan. Great Choice!' 
       replegchoice = raw_input ("What type of bill what you like congress to introduce?

       if replegchoice == 'a':

       if replegchoice == 'l': 
         print 'A popular idea, Republicans in Congress are sure to support this idea, as will many American voters!'
