Understand the Problem
The document appears to be a set of examination questions related to the Python programming language, including topics such as the developer of Python, its data types and operators, exceptions, and error handling.
Answer
Guido van Rossum developed Python. '.pyc' is used for Python compiled files. Data types: int, float, string, list, etc. Use 'def' for functions. 'Exception' catches all exceptions.
- Guido van Rossum developed Python. The '.pyc' extension represents a Python compiled file. Standard data types in Python include integer, float, string, list, tuple, dictionary, boolean, and set. String operators include concatenation (+), repetition (*), slicing ([::]), etc.
- (b) Python is a high-level, general-purpose programming language focused on code readability. A Python identifier is a name given to entities like variables and functions.
- Variable scope refers to the region where a variable is accessible. An 'if' statement executes code if a condition is true, e.g.,
if x > 0: print('Positive'). - Python advantages: easy syntax, large community. Disadvantages: slower execution. Lists are ordered collections, mutable, and allow duplicates, e.g.,
[1, 2, 3]. Common exceptions:ValueError,TypeError,IndexError,KeyError,ZeroDivisionError. - 'Exception' can catch all exceptions. Use 'def' to define user functions. Sorting algorithms: quicksort, mergesort, bubblesort, insertionsort, selectionsort. A 'try-finally' clause ensures finalization code runs regardless of exceptions. Exceptions manage errors gracefully, allowing for debugging and controlled exits.
