Looking to partially fill a fixed size array from file in python-CodePudding

I have to create an array with a fixed size and then fill partially from a data file. The fixed size needs to be 10 and there are three lines in the file. With my current code i get seven items in the array listed as ' ' how do I edit this code to just partially fill the array and ignore the empty spots?

MAX_COLORS = 10
colors = [''] * MAX_COLORS
counter = int(0)
filename = input("Enter the name of the color file (primary.dat or secondary.dat): ")
infile = open(filename, 'r')
line = infile.readline()
while line != '' and counter < MAX_COLORS:
    colors[counter] = str.rstrip(line)
    counter = counter   1
    line = infile.readline()
infile.close()

CodePudding user response：

The problem is in the following line:

colors[counter] = str.rstrip(line)

Should be:

colors[counter] = line.rstrip()

Explanation: Your variable line is an object of type str, and rstrip is a method of str. Calling line.rstrip() returns an rstripped copy of line.

As @ LarrytheLlama comments, try to use append:

# you do not need str() because rstrip() return str.
colors.append(rstrip(line))

Also you might want to remove 'counter' if you do not use it for other purpose.
