## 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
