In Python, variables are used to store data values and are created when you first assign a value to them. Python is dynamically typed, meaning you don’t need to declare the type explicitly — it’s inferred from the assigned value.
# Example: Different variable typesage = 25 # Integername = "Alice" # Stringheight = 5.6 # Floatis_student = True # Booleanprint(age, name, height, is_student)Copied!✕CopyThis will output:
25 Alice 5.6 TrueCopied!✕CopyCreating Variables You simply use the = operator to assign a value:
x = 10y = "Python"Copied!✕CopyVariables can change type during execution:
x = 42 # intx = "Now text" # strCopied!✕CopyMultiple Assignments Python allows assigning values to multiple variables in one line:
a, b, c = 1, 2.5, "Hello"p = q = r = 100 # same value to multiple variablesCopied!✕CopyType Checking & Casting Use type() to check a variable’s type:
print(type(a)) # <class 'int'>Copied!✕CopyConvert between types using casting functions:
num_str = "50"num_int = int(num_str)pi_str = str(3.14)Copied!✕CopyNaming Rules
