I want to iterate over each line of an entire file. One way to do this is by reading the entire file, saving it to a list, then going over the line of interest. This method uses a lot of memory, so I am looking for an alternative.
My code so far:
for each_line in fileinput.input(input_file): do_something(each_line) for each_line_again in fileinput.input(input_file): do_something(each_line_again)
Executing this code gives an error message:
The purpose is to calculate pair-wise string similarity, meaning for each line in file, I want to calculate the Levenshtein distance with every other line.
