  Python dictionary applications get built-in method
  Add Date : 2018-11-21      
  Python dictionary built-in methods get the application, if we need to get the value of the dictionary, we have two ways, one is through dict [ 'key'], the other one is dict.get () method.

Today is to share the dictionary get () method.

Here we can use a dictionary to do a little game, assume that the user enter the string in the terminal: "1" or "2" or "3", returns the corresponding content if other input, then return "error"

Here some people may use if elif else statements to determine the operation, indeed, but more complicated. We recommend a dictionary of get () method is very convenient.

info = { '1': 'first', '2': 'second', '3': 'third'} number = raw_input ( 'input type you number:') print info.get (number, 'error') Thus, you may get a line of code can be done python judge sentences a few lines of code.
