How To Efficiently Check For Variables In A For Loop
I have eight variables that i want to check agianst the current line in the for loop. I think there might be a better way to do this than what i currently have.
I now have 5 different if statements
with open('stuff.txt', 'r') as f: lines = f.read().splitlines() for line in lines: if line == str(sameDay): bag.append(line) if line == str(threeDaysAgo): bag.append(line) if line == str(weekAgo): bag.append(line) if line == str(monthAgo): bag.append(line) if line == str(threeDaysAgo): bag.append(line)
Better than having many
if statements, and also more efficient that calling on
append multiple times.
variables = set(map(str, [sameDay, threeDayAgo, weekAgo...])) def check_variables(lines): for line in lines: if line in variables: yield line
Edit: Made variables into a
set since it runs
in faster than a
list. Useful if
lines is really long.
