Python Math: Print the floating point from mantissa, exponent pair

Python Math: Exercise-58 with Solution

Write a Python program to print the floating point from mantissa, exponent pair.

Sample Solution:-

Python Code:

import math

print('{:^7}  {:^8}  {:^17}'.format('Mantissa', 'Exponent', 'Floating point value'))
print('{:-^8}  {:-^8}  {:-^20}'.format('', '', ''))

for m, e in [ (0.7, -3),
              (0.3,  0),
              (0.5,  3),
              ]:
    x = math.ldexp(m, e)
    print('{:7.2f}  {:7d}  {:7.2f}'.format(m, e, x))
	

Sample Output:

Mantissa  Exponent  Floating point value                                                                      
--------  --------  --------------------                                                                      
   0.70       -3     0.09                                                                                     
   0.30        0     0.30                                                                                     
   0.50        3     4.00

Python: Unpack a Tuple

>>> items = (0, 'b', 'one', 10,  11, 'zero')
>>> a, b, c, d, e, f = items
>>> print(f)
zero
>>> a, *b, c = items
>>> print(b)
['b', 'one', 10, 11]
>>> *_, a, b = items
>>> print(a)
11
