c ++地图 <int, int> 在python中

Question

Does anyone know the c++ equivalent on python? Initially I thought I could replicate this by initializing a simple array on python, but it obviously does not do the same. Any ideas?

map<int, int>

Kind Regards and many thanks,

Rodrigo

Answer 1

Yes but remember that python objects are not statically typed so a declaration like this map is not needed (and would not work) What you do in python is declare an empty dictionary and add ints to it.

Example:

my_map = {} #empty dictionary
my_map[1] = 100
my_map[2] = 150

But there would be no problem continuing adding objects of different types to the dictionary:

my_map[3] = "Hello world"

and changing the type of the existing objects:

my_map[1] = "Hello again"

Answer 2

You can use dict

elevators = {}
clone_floor, clone_pos = map(int, raw_input().split())
elevators[clone_floor] = clone_pos

Hope this helps.

Answer 3

It is called a dictionary. One of the most powerful features in Python. See here for the documentation.

d = dict()
d[1] = 5
d[5] = 2
print d[1]
print d[5]

Answer 4

elevators = {}
elevatorFloor, elevatorPos = map(int, raw_input().split())
elevators[elevatorFloor] = elevatorPos

This should work in Python 2.

Answer 5

Managed to get it sorted. Some syntax errors we all missed but here's the correct way:

elevators = {}

elevators['clone_floor'] = clone_pos

This works.

Thanks again!
