input()
語法
msg = input("提示訊息")
input傳回值是str，若輸入為數字，需要使用int(input("提示訊息")),float(input("提示訊息"))函式轉型。

name = input("請輸入姓名:")
age = input("請輸入年齡:")
score = input("請輸入成績:")
print("name = ", name)
print("age = ", age)
print("score = ", score)
print("type of score = ", type(score))
print("type of age = ", type(age))
請輸入姓名:Mary
請輸入年齡:18
請輸入成績:88.5
name = Mary
age = 18
score = 88.5
type of score = <class 'str'>
type of age = <class 'str'>
以下程式碼會錯，因為score是str，需強制轉型。
1
print("score + 10 = ", score + 10)
print("score + 10 = ", score + 10)
~~~~~~^~~~
TypeError: can only concatenate str (not "int") to str
強制轉型後的結果如下:

name = input("請輸入姓名:")
age = input("請輸入年齡:")
score = input("請輸入成績:")
print("name = ", name)
print("age = ", age)
print("score = ", score)
print("score + 10 = ", float(score) + 10)
請輸入姓名:Mary
請輸入年齡:age
請輸入成績:88.5
name = Mary
age = age
score = 88.5
score + 10 = 98.5
