Python Functions important MCQs in English/Hindi | Nielit Notes | PDF

In this post, we cover all important Questions from the topic "Python Functions".

These MCQs will definitely help to pass IT and Computer students in any exam and interview that have Pyhton Functions topic.

The Python Functions chapter covers the following topics:

Top-down approach of problem solving, Modular programming and functions,

Function parameters, Local variables, the Return statement, DocStrings, global

statement, Default argument values, keyword arguments, VarArgs parameters.

Library function-input(), eval(),print(), String Functions: count(), find(), rfind(),

capitalize(), title(), lower(), upper(), swapcase(), islower(), isupper(), istitle(),

replace(), strip(), lstrip(), rstrip(), aplit(), partition(), join(), isspace(), isalpha(),

isdigit(), isalnum(), startswith(), endswith(), encode(), decode(), String: Slicing,

Membership, Pattern Matching, Numeric Functions: eval(), max(), min(), pow(),

round(), int(), random(), ceil(), floor(), sqrt(), Date & Time Functions, Recursion

After completion of the Python Functions unit, Students will be able to: 

• Apply the in-built functions available in Python in solving different problems.
