Below are 5 simple Python Programming Language questions which can be asked in a Python Related job interview.
Q. 1 – Write a Python Program to count occurrences of characters in a word.
import collections
counters = collections.Counter("Computer")
print(counters)
# Prints out Counter({'C': 1, 'o': 1, 'm': 1, 'p': 1, 'u': 1, 't': 1, 'e': 1, 'r': 1})Q. 2 – Write a Simple Lambda Expression?
sumlambda = lambda x, y : x + y
print(sumlambda(4, 5))Q. 3 – What is filter keyword in Python Programming Language?
The filter function is a utility function which can skip values based on some condition.
a_list = [3, 4, 5, 6, 7, 8, 9]
for i in filter(lambda x: x % 2 == 0, a):
print(i)Q. 4 – Explain Reading/Writing Files in Python Programming Language?
Writing a File in Python
f = open('hello.txt','w') # opens a file in write mode
f.write('ComputerScienceHub Website') # writes this line in file
f.close() # closes the fileReading a File in Python
f =open('hello.txt','r') # opens a file in read mode
text = f.read() # reads the entire contents of file in memory
print(text) # prints the read text
f.close() # closes the fileQ. 5 – Best way to read a File in Python?
with open("hello.txt", "r") as f:
for line in f:
print(line)Above code block after it ends will automatically close file hello.txt without programmer need to explicitly do it using f.close()
