Introduction<\/h2>\n

The find() function in Python is used to check if a substring is in a string according to the start and end values \u200b\u200byou set. This function is almost the same as the index() function.<\/p>\n

If present, the function will print the lowest index of that substring. Otherwise, it will return -1.<\/p>\n

And the article below, we will show you how to use the find() function in Python through several examples as go through below.<\/p>\n

Example<\/h2>\n
str = \"Welcome to Python\"\r\n\r\nx = str.find(\"to\")\r\n\r\nprint(x)<\/pre>\n
Output:<\/p>\n
8<\/strong><\/p>\n
Definition<\/h2>\n
The find() function finds the lowest position of the substring.<\/p>\n
If not found, it will return -1.<\/p>\n
The syntax<\/h2>\n
$ string.find(value, start, end)<\/pre>\n
Parameter Values<\/strong>:<\/p>\n
value: substring that you need to find<\/p>\n
start: starting value. Default is 0<\/p>\n
end: ending value. Default is the end of the string<\/p>\n
More examples<\/h2>\n
Example 1<\/strong>: Find the word “e”<\/p>\n
str = \"Welcome to Python\"\r\n\r\nx = str.find(\"l\")\r\n\r\nprint(x)<\/pre>\n
Output:<\/p>\n
1<\/strong><\/p>\n
Example 2<\/strong>: Find the word “e” from position 3 to position 10<\/p>\n
str = \"Welcome to Python\"\r\n\r\nx = str.find(\"e\", 3, 10)\r\n\r\nprint(x)<\/pre>\n
Output:<\/p>\n
6<\/strong><\/p>\n
Example 3<\/strong>: try to find a substring that does not appear<\/p>\n
str = \"Welcome to Python\"\r\n\r\nx = str.find(\"a\")\r\n\r\nprint(x)<\/pre>\n
Output:<\/p>\n
-1<\/strong><\/p>\n
