VS2013 Learning notes in Python [Basic primer]

Objective

In the previous section, we briefly describe how to develop Hello World in VS2013, and build an environment http://www.cnblogs.com/aehyok/p/3986168.html in VS2013. This section is primarily about learning the basics of Python.

Getting Started with Python basics

1. Print a string Hello world.

Print ('HelloWorld')

2. Print a path

Print ('C:\aehyok\aehyok')

It can be found that \a has escaped. If you do not want to escape, simply add an R to the string before

Print (R'C:\aehyok\aehyok')

3. String concatenation and string repetition times

Print ('str'+'ing','aehyok  '*3)

4, the string two index way, from left to right index starting from 0, right-to-left index starting from 1.

word='aehyok'print (word[0],word[5]) print (word[- 1],word[-5])

5, the string is sliced: separated by a colon two index, the form of the variable [head subscript: Tail subscript]. The range of interception is before and after closing.

cat='aehyok'print (cat[3:]) print (cat[3:6  ]) print (cat[:-1]) print (cat[-1])

6. Get typed string and print string and string length and type

Object = input (") print ("Get Anlu integeris") ,object, type (object), Len (object))
