Python: Compute the square of first N Fibonacci numbers, use map function and generate a list of the numbers
Python map: Exercise-10 with Solution
Write a Python program to compute the square of first N Fibonacci numbers, using map function and generate a list of the numbers.
Fibonacci numbers:
From Wikipedia,
In mathematics, the Fibonacci numbers, commonly denoted Fn, form a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones, starting from 0 and 1. That is,
F0 = 0, F1 = 1,
and
Fn = Fn - 1 + Fn - 2,
for n > 1.
The beginning of the sequence is thus:
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144,....
Sample Solution:
Python Code :
import itertools
n = 10
def fibonacci_nums(x=0, y=1):
yield x
while True:
yield y
x, y = y, x + y
print("First 10 Fibonacci numbers:")
result = list(itertools.islice(fibonacci_nums(), n))
print(result)
square = lambda x: x * x
print("\nAfter squaring said numbers of the list:")
print(list(map(square, result)))
Sample Output:
First 10 Fibonacci numbers: [0, 1, 1, 2, 3, 5, 8, 13, 21, 34] After squaring said numbers of the list: [0, 1, 1, 4, 9, 25, 64, 169, 441, 1156]

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
