What is the most efficient way to run this kind of python code?-CodePudding

I was coding a discord bot and realized I had difficulty parsing messages. I ended up using a double for loop (yuck). What can I do to optimize this code? (this is a far more straightforward version of the code)

string = "His name is food"
list = ["food", "numbers"]
parsed_string = string.split(" ")
print(parced_string)

for i in parsed_string:
  for x in list:
    if i == x:
      print("stop")

How do I optimize this bit of code?

CodePudding user response：

string = "His name is food"
list = ["food", "numbers"]
parsed_string = string.split(" ")
print(parsed_string)

for i in parsed_string:
  if i in list:
     print("stop")

CodePudding user response：

For a long list of keywords, prefer a dictionary.

string = "His name is food"
list = {"food": None, "numbers": None]
parsed_string = string.split(" ")
print(parsed_string)

for i in parsed_string:
  if i in list:
     print("stop")

CodePudding user response：

string = "His name is food"
mylist = ["food", "numbers"]

if set(string.split()).intersection(mylist):
    print("stop")

if not set(string.split()).isdisjoint(mylist):
    print("stop")
