Answer 1

try to store the file.read.splitlines in a variable and take only lines ito print, like: var a = file.read.splitlines and later in printf call just do a[i]

Answer 2

I don't know what was your initial not working code, as you've edited it... but:

> I think your main mistake is to compare user entry (x) with 1 rather than '1' (number instead of string)...

> What I would do would be:

i=0
# using 'with' statement the stream (file here) is implicitly close at end of block
with open('ex15_sample.txt') as file:
for line in file:
print(line)
x=input("please press 1 to continue \n" )
if x=="1" and i < 3:
i += 1
else:
print("goodbye")
break

Answer 3

thank you so much paul it work! Though may i ask why it didn't work before? what did storing file.read.splitlines to a help in?

Answer 4

i may be 60% wrong cause i dont know how exacly file.read works, but i assumed that: a) the file.read have to open a file so it does it and it is kept open. in the next loop run it pretrnds to open file once more but it is hold by another process, or b) it opens file once and read all lines and in the next loop it already rode all lines so whats left? i,m keen to version a) tho

Answer 5
