Create multiple array depending on a variable-CodePudding

I would like to create in Python multiple arrays whose names depend on a variable j, like this:

for j in range(30):
    x_j = np.loadtxt(f'Fid{j}.txt','r', unpack = True)

and the result would be to create 30 arrays x0, x1 .... x29. (Of course this code won't work).

I cannot make a matrix because each of this txt files has a different length, and I don't want to fill them with zeros because it would change a lot.

Do you have some ideas?

CodePudding user response：

You can use a dictionary where the key is j and value is the array itself

CodePudding user response：

Maybe it helps you to ask yourself, why you would want to create 30 independent variables for 30 different arrays in the first place?

Creating a dictionary with j as the key variable probably is the better way.

E.g.

x = dict()
for j in range(30):
   x[j] = np.loadtxt(f'Fid{j}.txt','r', unpack = True)

You can then acess each of these arrays easily by the "variables" x[0], x[17], or x[29] wherever you need to access them later in your code.
