i don't really know why, but Spyder is not able to show lists or arrays in the variable explorer anymore. Do you have the same problem, any fixes? I have that problem on two computers.
Example:
CSV = []
for x in os.listdir(location):
if x.split(".")[-1] =="CSV":
CSV.append(location+x)
CSV = np.array(CSV)
Thank you very much!
