恳请家人们看看这个咋搞鸭

a=eval(input().replace(' ',','))
print(f"sum = {sum(a)}; averager = {round(sum(a)/len(a),2)}",end='')

grades = input("请输入成绩：").split(" ")                 
grade = [float(i) for i in grades]                  
print("sum =" + str(sum(grade)) + ";", end=' ')     
print("average =", round(sum(grade)/len(grade), 2), end='')
