My python program encounters an error when trying to assign a value to an array, can someone please help me?

My code looks like the following:

elif(cmdIn == "repeatultilineString"):

        lines = []
        currentLine = 0
        ask = True
        while(ask):
            newLine = input("Line " + str(currentLine + 1) + " value(\"end\" to finih line setup): ")
            if(newLine == "end"):
                ask = False
            else:
                lines[currentLine] = newLine
                currentLine = currentLine + 1
        times = input("Input repetition times: ")
        interval = input("Input interval(in seconds) between each repetition(0 for quickest repetition): ")
        i = 1
        while(i<float(times) + 1):
            print(str(i) + ":\n")
            j = 0
            while(j<currentLine):
                print(lines[j] + "\n")
                j = j + 1
            time.sleep(float(interval))
            i = i +1

and the output is:

C:\Terminal>>>repeatMultilineString
Line 1 value("end" to finih line setup): hello
Traceback (most recent call last):
  File "/home/main.py", line 51, in <module>
    lines[currentLine] = newLine
IndexError: list assignment index out of range

Can someone help me fix this?

Best answer

Instead of

lines[currentLine] = newLine

use

lines.append(newLine)

That should work. (I did not test as you only gave part of the code.)
