String search in Python list

Posted under » Python updated on 3 Dec 2025

You can assign a multiline string to a variable by using three quotes

a = """LK Y is
a cool dude in Hell."""

b = '''Goh C cant
wait to join LK Y.'''

To get the length of a string, use the len() function

a = "Hello World!"
print(len(a))

Strings in Python are arrays of bytes representing unicode characters.

a = "Hello World!"
print(a[1])

To check if a certain phrase or character is present in a string, we can use the keyword in.

txt = "Hello World"
if "Hell" in txt:
  print("Yes, 'Hell' is present.")

The good thing about `in' is that it is not case sensitive. So hello and Hello will be found. Here is an example in list

myls = ['Hello from Anoneh', 'Hello', 'Hello boy!', 'Hi']
for gay in myls:
    if "Hell" in gay:
        print("Yes, 'Hell' is present.")
    else : 
        print("Not this time")

Check if "cool" is NOT present in the following text:

txt = "Hello World"
if "cool" not in txt:
  print("No, 'cool' is NOT present.")

If you want to check the number (count) of `l' in "Hello World",

txt = "Hello World"
counter = txt.count('l')

List example

a = [1, 2, 3]
b = 4
if b in a:
    print('4 is present!')
else:
    print('4 is not present')

You can see that it is exact when integer

For string, you can use the ‘any()’ method. The any() method in Python can be used to check if a certain condition holds for any item in a list. This method returns True if the condition holds for at least one item in the list, and False otherwise.

For example, if you wish to test whether ‘anoneh’ is a part of any of the items of the list, we can do the following:

myls = ['Hello from Anoneh', 'Hello', 'Hello boy!', 'Hi']
 
if any("Anoneh" in word for word in myls):
    print('\'Anoneh\' is there inside the list!')
else:
    print('\'Anoneh\' is not there inside the list')

Note that it is case sensitive.
