I know how to handle this with one file. But I don't know how to do that
with more than one.
So the program should try and open all 10 files and if, and only if, none
of the files exists I want en error message to appear.

Use a counter which increments with every existing file. After opening

Or, if you need to know which files exist, use a list, append existing
files to it and check at the end if it's not empty.
Do you need more help?
Andreas,
Thanks for your answer. I am afraid I don't understand this:
"Use a counter which increments with every existing file. After opening
all files check if the counter is bigger than 0."
I thought I could co along those lines earlier
try:
text_file=open("Hey","r") and text_file1=open("Hey","r")
except:
print("hi")
So that hi is printed only and only if both files aren't existing.
Thank you!
