-   Given a string representing one Unicode character, return an integer representing the Unicode code point of that character.
+      The pow() function returns the power of a number.It takes two or three arguments:
+      pow(base, exp): Returns base raised to the power of exp (base ** exp).
+      pow(base, exp, mod): Returns (base ** exp) % mod (for modular arithmetic).
+      Result is computed more efficiently than base ** exp % mod, if mod arg is present.

 ## Example
 
 ```python
->>> result = pow(2, 3)
->>> print(result)
+# Basic exponentiation
+>>> pow(2, 3)
 # 8
+
+# Using three arguments (modular exponentiation)
+>>> pow(2, 3, 5)
+# 3  (since 2^3 = 8, and 8 % 5 = 3)
+
+# Works with negative exponents (returns float)
+>>> pow(2, -3)
+# 0.125  (since 2^(-3) = 1/8)
