Deleting a hyphen from a text file output, but not the hyphen on negative numbers

Question

I have a text file with lots of numbers, one integer/float per line.
Blank lines with no data are indicated with a '-' and id like to remove the hyphen with code. But, while doing that, avoid removing the hyphen from negative numbers (-4 etc).
Is this possible to begin with?

I have tried using str.replace and str.split with no success as it either removes all the hyphens or none.

Answer 1

this will remove all trailing - from the line. If the line contained spaces you can change num.rstrip("-") to num.strip().rstrip("-")

with open("your_file") as fp:
    file_content = [num for num in fp if num.rstrip("-")]
