형식 오류 : 단항 +에 대한 잘못된 피연산자 유형 : 'STR'는

Question

이 내 코드입니다 -

import random 
symbols=["+","-","x"] 
question=0 
score=0 
choice=0 
name=input("What is your name?") 
while question<10: 
    r1=random.randint(1,10) 
    r2=random.randint(1,10) 
    s1=random.choice(symbols) 
    add=(r1+r2) 
    sub=(r1-r2) 
    times=(r1*r2) 
    print("What is ",+str(r1),+s1,+str(r2),) 
    ask=int(input()) 
    if s1=="+": 
     if ask==add: 
      print("Correct") 
      score=score+1 
     else: 
      print("Incorrect") 
    if s1=="-": 
     if ask==sub: 
      print("Correct") 
      score=score+1 
     else: 
      print("Incorrect") 
    if s1=="x": 
     if ask==sub: 
      print("Correct") 
      score=score+1 
     else: 
      print("Incorrect") 
print("Your score is: "+score,"out of 10") 

와 내가 오류입니다 -

What is your name?Emma 
    Traceback (most recent call last): 
     File "C:/Users/Emma/Documents/Python/Questions Maths.py", line 14, in <module> 
     print("What is ",+str(r1),+s1,+str(r2),) 
    TypeError: bad operand type for unary +: 'str' 

Answer 1

당신은 쉼표 제거해야합니다

을

print("What is " +str(r1)+s1+str(r2)) 
print("What is", r1, s1, r2) 

마지막 줄 :

print("Your score is: " + score + "out of 10") 

그러나 더 파이썬 방법으로 당신이 사용할 수있는 % 또는 format :

print("What is {0}{1}{2}".format(r1,s1,r2)) 

OR :

print("What is %d%s%d" % (r1,s1,r2)) 

Answer 2

당신은 라인을 변경해야합니다 :이이 옵션을

print("What is ",+str(r1),+s1,+str(r2),) 

을

플로트

0 정수

%f.2위한 문자열

%d위한

print("What is "+ str(r1) + s1 + str(r2))

print("What is %d %s %d" % (r1,s1,r2))

print("What is", r1, s1, r2)

• 그리고 당신은 또한 당신의 마지막 줄을 변경해야합니다 :

  print("Your score is: "+score,"out of 10") 
  

  를 들어 :

  1. print("Your score is: "+ score +" out of 10")
  2. print("Your score is: %s out of 10" % score)
  3. print("Your score is:", score, "out of 10")
