回答错了！再试一次：I_uuua boy

您实际上没有从用户那里获得任何输入，当您写入start=input时，您将变量start设置为与内置函数input相等。要实际获取输入，需要使用start=inputprompt，如图所示

print("Welcome! Type in 'Enter' (without apostrophes) to begin")
start = input
if start == "Enter":
 print "Fill in the blanks: I __ a boy"
answer = input
if answer != "am":
 print "Wrong answer! Try again: I __ a boy"
if answer == "am":
print "Congratulations!"

start = input("Welcome! Type in 'Enter' (without apostrophes) to begin")
if start == "Enter":
    answer = input("Fill in the blanks: I __ a boy")
    if answer != "am":
        print "Wrong answer! Try again: I __ a boy"
    elif answer == "am":
        print "Congratulations!"
