why it doesnt match next

in this example: import re pattern = r"^gr.y

quot; if re.match(pattern, "grey"): print("Match 1") if re.match(pattern, "gray"): print("Match 2") if re.match(pattern, "stingray"): print("Match 3") if re.match(pattern, "grstingray"): if the string starts with gr. Its the third "if sentence"" why it doesn't match with the regular expression : r"^gr.y
quot; ?

Your RegEx means : first character : g second character : r third character : anything fourth and last character : y So stingray has more than 4 character like grstingray

so import re pattern = r"^gr..y
quot; if re.match(pattern, "greey"): print("Match 1") if re.match(pattern, "gray"): print("Match 2") if re.match(pattern, "gramystingray"): print("Match 3") if re.match(pattern, "gramy"): print("Match 4") result: Match 1 Match 4

Yes because it needs exactly 2 characters between r and y
