答

high = 100 
low = 0 
print('Please think of a number between 0 and 100!') 
while True: 
    middle = (high + low) // 2 
    print('Is your secret number ' + str(middle)) 
    ans = input("Enter 'h' to indicate the guess is too high. Enter 'l' to indicate the guess is too low. Enter 'c' to indicate I guessed correctly.") 
    print(ans) 
    if ans == 'h': 
     high = middle 
     print('Is your secret number ' + str(middle)) 
    elif ans == 'l': 
     low = middle 
     print('Is your secret number ' + str(middle)) # This line lacks of ')' in your code. 
    elif ans == 'c': 
     break 

print('your secret num is ' + str(middle))

ans该不能被分配给high或low。它是middle将被分配到high或low。
