Python Math: Display the fraction instances of the string representation of a number

Python Math: Exercise-43 with Solution

Write a Python program to display the fraction instances of the string representation of a number.

Sample Solution:-

Python Code:

import fractions

for s in ['0.7', '2.5', '9.32', '7e-1']:
    f = fractions.Fraction(s)
    print('{0:>4} = {1}'.format(s, f))

Sample Output:

 0.7 = 7/10                                                                                                   
                                                                                                              
 2.5 = 5/2                                                                                                    
                                                                                                              
9.32 = 233/25                                                                                                 
                                                                                                              
7e-1 = 7/10
