str = input(tipmsg)
说明:
a = input("Enter a number: ")
b = input("Enter another number: ")
print("aType: ", type(a))
print("bType: ", type(b))
result = a + b
print("resultValue: ", result)
print("resultType: ", type(result))
运行结果示例:
Enter a number: 100↙
Enter another number: 45↙
aType: <class 'str'>
bType: <class 'str'>
resultValue: 10045
resultType: <class 'str'>
↙表示按下回车键,按下回车键后 input() 读取就结束了。+起到了拼接字符串的作用,而不是求和的作用。
a = input("Enter a number: ")
b = input("Enter another number: ")
a = float(a)
b = int(b)
print("aType: ", type(a))
print("bType: ", type(b))
result = a + b
print("resultValue: ", result)
print("resultType: ", type(result))
运行结果:
Enter a number: 12.5↙
Enter another number: 64↙
aType: <class 'float'>
bType: <class 'int'>
resultValue: 76.5
resultType: <class 'float'>
a = input("Enter a number: ")
b = input("Enter another number: ")
print "aType: ", type(a)
print "bType: ", type(b)
result = a + b
print "resultValue: ", result
print "resultType: ", type(result)
在 Python 2.x 下运行该代码:
Enter a number: 45↙
Enter another number: 100↙
aType: <type 'int'>
bType: <type 'int'>
resultValue: 145
resultType: <type 'int'>
