What are common string operations?

Common string operations in Python include:

1. Concatenation: Joining two or more strings together.

   full_name = "John" + " " + "Doe"  # "John Doe"

2. Repetition: Repeating a string multiple times.

   echo = "Hello " * 3  # "Hello Hello Hello "

3. Length: Getting the number of characters in a string.

   length = len(full_name)  # 8

4. Indexing: Accessing individual characters using their position.

   first_char = full_name[0]  # 'J'
   last_char = full_name[-1]   # 'e'

5. Slicing: Extracting a substring from a string.

   substring = full_name[0:4]  # "John"

6. Changing Case: Converting strings to upper or lower case.

   upper_case = full_name.upper()  # "JOHN DOE"
   lower_case = full_name.lower()  # "john doe"

7. Finding Substrings: Checking if a substring exists within a string.

   index = full_name.find("Doe")  # 5

8. Replacing Substrings: Replacing parts of a string with another string.

   new_name = full_name.replace("Doe", "Smith")  # "John Smith"
