python - TypeError：字符串对象不可调用

Question

我在第 4 行得到了这个TypeError。print("I'm "+ ageStr +"years old.")我已经尝试过 f-strings，甚至str(ageStr) / str(age)- 我在第 4 行仍然遇到同样的错误。

ageStr = "24" #I'm 24 years old.
age = int(ageStr)

print("I'm "+ ageStr +"years old.")
three = "3"

answerYears = age + int(three)

print("The total number of years:" + "answerYears")
answerMonths = answerYears*12 

print("In 3 years and 6 months, I'll be " + answerMonths + " months old"

Answer 1

这是您的错误的解决方案，

print("In 3 years and 6 months, I'll be " + str(answerMonths) + " months old")   

第二种解决方案是简单地删除字符串连接，

print("In 3 years and 6 months, I'll be ", answerMonths, " months old")
