I'm trying to read a text file with matrix and put it in a list, but I am using two loops here and I want my function to be faster.
def read_file(path_to_file):
mylist=[]
for eachLine in open(path_to_file,'rt'):
mylist.append([int(eachRow) for eachRow in eachLine.split()])
return mylist
Not sure if it's possible to make this faster. But it can be better:
with open(path_to_file, 'rt') as fh:
return [[int(value) for value in line.split()] for line in fh]
First of all, you should always use a with ... context manager when working with files. That way you cannot forget to close the file handle after you are done reading from it.
Other improvements:
Also keep in mind PEP8, the Python style guide.
intcan handle only one number at a time, you have to have 2 loops of some sort. \$\endgroup\$
