๐Ÿ“š Quick Study Guide

  • ๐Ÿ” What are Strings? Strings are sequences of characters used to represent text in Python. They are immutable, meaning they cannot be changed after creation.
  • ๐Ÿ”— Creating Strings: Strings can be created using single quotes (' '), double quotes (" "), or triple quotes (''' ''' or """ """) for multi-line strings.
  • โœ‚๏ธ String Slicing: Accessing parts of a string using indexing and slicing. For example, `string[start:end:step]`.
  • โž• String Concatenation: Combining strings using the `+` operator. For example, `string1 + string2`.
  • ๐Ÿ”จ String Methods: Python provides numerous built-in methods for string manipulation, such as `.upper()`, `.lower()`, `.strip()`, `.replace()`, `.find()`, and `.split()`.
  • ๐Ÿ”ข String Formatting: Using f-strings or the `.format()` method to insert variables into strings. For example, `f"Hello, {name}!"` or `"Hello, {}".format(name)`.
  • ๐Ÿงฎ Escape Sequences: Special characters represented with a backslash, like `\n` (newline), `\t` (tab), and `\"` (double quote).
