I'm starting in python and I use a site that has several problems for resolution, in it the vectors and arrays are passed with values separated by a space and not comma. For example: v = 1 2 3 43.
I know I can get this value in the input and leave it as a string, the question is how to make that string into a vector. I would like to know if there is any function that can convert, because if I am to "handle" this input I lose efficiency.
If this is what you want, to receive a string with number and then convert them, use the following code:
>>> s = "1 2 3 56 88"
>>> map(int, s.split())
[1, 2, 3, 56, 88]
Explaining: s.split() transforms a string into a vector, using the parameter as a delimiter. The default value of the delimiter (which is hidden) is space.
After that, it is passed as input to the map function. It simply performs a function for each element in the list. In this case, it will pass to the function int , which converts a string to integer.
Note that it will generate a ValueError ception exception if it does not successfully convert.
Well let's go
Is it possible for you to install the numpy module?
The numpy is highly recommended when you start working with vectors and array, it actually breaks a giant branch.
Your problem would be solved like this:
import numpy as np
v = "1 2 3 43"
teste=v.split()
vetor = np.asarray(teste)
I do not know if this is what you want, but I hope it helps: a = map (int, input (). split ()) In this case the vector a receives a list of ints separated by space, comma, bar, etc.
