Pre-Defined function in python programming :- दोस्तों अगले पाठ में आप ने जाना की function क्या होता है ? और कितने प्रकार का होता है ?
आज पाठ में हम Pre-Defined function के बड़े में विस्तार से पढ़ेंगे |
Pre-Defined function ऐसे reusable code का समूह होता है जो की किसी programming language में पहले से बनाया हुआ होता है | ताकी उनका उपयोग हम अपने जरुरत के अनुसार कभी भी program में कर सके |
