What are the key features of Python?
- Dynamically typed – In Python, you don’t have to state the variable kinds. You can easily run
x=111and thenx="I'm a string"without error. - Interpreted language – This means Python doesn’t have to be compiled before running. PHP and Ruby are other interpreted languages.
- Object oriented programming – Python is highly suitable for such kind of programming. It lacks access specifiers (like C++’s
public,private>).
What role does PYTHONPATH environment variable plays?
PYTHONPATH works similar to a PATH. It helps Python interpreter in locating the module files imported into a program. It includes Python source library directory as well as the directories comprising the Python source code.
Name the supported data types in Python.
Python has 5 supported data types:
- Numbers
- List
- String
- Dictionary
- Tuple
Do you know how to display contents of text file in a reverse order?
- Change the given file into a list,
- Then reverse the list by using reversed()
- Eg: for line in reversed(list(open(“file-name”,”r”))):
- Print(line)
Pick out the invalid statement from below.
- a) abc = 1,000,000
- b) a b c = 1000 2000 3000
- c) a,b,c = 1000, 2000, 3000
- d) a_b_c = 1,000,000
Answer: b
How do you manage memory in Python?
- Python private heap space manages its memory. All Python items and data structures are stored in a private heap. The programmer is not given access to this, but an interpreter manages this heap.
- Pythom memory manager allocates Python heap space, while giving some access to the programmer for coding.
- Python comprises of an inbuilt garbage collector – it recycles all the redundant memory, frees the extra memory and feeds it into the heap space.
What do you mean by Python dictionary?
Python dictionary is nothing but built-in datatypes. It entails a one-to-one relationship between keys and values. Dictionaries are indexed by keys; they contain pairs of keys and their corresponding values.
