Python Dict as a comparison of key values with 1 and true

Operating Environment:

Operating system: Win7 64-bit

Python version: 2.7.12

Ide:pycharm 2017.2

Test code:

Test Python dict 1 and True as a key value

The test demo is as follows:

#!/usr/bin/env python

"Liukang"


Dict_test = {}
Print Dict_test
dict_test[1
Print Dict_test
dict_test[True
Print Dict_test

The results appear as follows:

As can be seen, first we create a new dict:{1:1}, followed by the update into {1:true}. Describes the key value 1=true in Python's dict, but it is important to note that 1 is not equal to True in value.

　

Similarly, let's test if 0 in Python dict key is equivalent to False:

Test Demo:

Dict_test = {}
Print Dict_test
dict_test[0
Print Dict_test
dict_test[False
Print Dict_test

The results are as follows:

Describes the key value 0=false in Python's dict,

Summarized as follows:

Describes the key values 1=true, 0=false, in Python's dict, but it is important to note that 1 in value is equal to True, and 0 is not equal to False.
