Python3 (b) simple input and output and built-in function view

After working with a girlfriend to learn Python3, code is she knocked, a little spicy eyes, only for reference.

1. Title: Enter "name", output "Hello, name"

For instructions on installing and opening the Python shell, refer to this: http://www.jb51.net/article/129327.htm

File>new file Enter the following code

Python3 Code:

Name = Input ("Enter your Name:") print ("Hello,", name)

2. Play a word game and guess the height.

Python3 Code:

Print ("......") I love Willie ... ') tall = input ("You know how Tall Willie is:")  guess = Int (tall)       #将tall强制转型赋值给guessif guess = = 190:       #判断 Print ("Your sister, it all knows!") ") Print (" bingo!! Guess right, you're awesome! Else:print ("Really stupid, don't want to play with you, Goodbye.") ") Print (" Granville is the best!!! ")

Results:

3. Built-in functions

Python3 view statements for built-in functions:

Dir (__builtins__)

If you want to know the specific function and usage description of a function, say int, use the following statement:

Help (int)  #help加内置函数名称, you can find out the function and usage.
