The main problem with search methods in Python is that they are not optimized for speed. This can slow down your program significantly.
The search method in python can be used to find a substring in a given string. This method returns the index of the first occurrence of the substring in the string. If the substring is not found, it returns -1.
Example:
str = "Hello world"
print str.search("world")
Output: 6
Search
In Python, you can use the built-in search function to find specific items in a sequence of data. The search function takes two arguments: the sequence to search and a keyword or pattern to look for.
To search for all items that have the word “cat” in them, you could use the following code:
print(“Searching for ‘cat’…”) search = “cat” print(“Found %d items.” % (len(search)))
The output of this code would be:
Searching for ‘cat’… Found 5 items.
Methods
There are many different methods in Python. Some of the most common methods are listed below.
def: This is a function that takes one or more arguments. The function will return a value.
print: This prints the text string to the screen.
if: This tests if a condition is true. If it is, the code inside the if block will be executed, otherwise it will not be executed.
