Python String Cheat Sheet

===========================
Python String Cheat Sheet
===========================

Strings are

• Indexed
• Iterable
• Immutable

Indexing & Slicing

———————————–

s = "python"

s[0]      -> 'p'
s[-1]     -> 'n'

Slicing:
s[start:end]       -> s[1:4] = 'yth'
s[:3]               -> 'pyt'
s[3:]               -> 'hon'
s[::2]              -> 'pto'
s[::-1]             -> reversed string

1. Functions

• Defining a Function:

  python
  def function_name(parameters): # Code block

• Calling a Function:

  python
  function_name(arguments)

• Default Parameters:

  python
  def greet(name="User"): print(f"Hello, {name}!") greet() # "Hello, User!" greet("Alice") # "Hello, Alice!"

• Return Statement:

  python
  def add(a, b): return a + b result = add(3, 5) # result is 8

• Function Scope (Local vs Global):

  • Local variables are accessible only within the function.
  • Global variables are accessible

typedef struct student{
   
    char name[30];
    char student_Ids[50]; 
    int student_grades[10];
    int gradeavg;
    
}student;

void print_students (student[], int);
student return_student(student[], int, char []);
