Python Math: Round a specified decimal by setting precision

Python Math: Exercise-40 with Solution

Write a Python program to round a specified decimal by setting precision (between 1 and 4).

Sample Solution:-

Python Code:

import decimal

d = decimal.Decimal('00.26598')
print("Original Number : ",d)
for i in range(1, 5):
    decimal.getcontext().prec = i
    print("Precision-",i, ':', d * 1)

Sample Output:

Original Number :  0.26598                                                                                    
Precision- 1 : 0.3                                                                                            
Precision- 2 : 0.27                                                                                           
Precision- 3 : 0.266                                                                                          
Precision- 4 : 0.2660

Python: Tips of the Day

Getting rid of unwanted characters:

You can get rid of whitespaces or any specific character using strip methods in Python. You can use either plain strip for both sides, lstrip for the left side and rstrip for the right side only.

str="+++Welcome python+++"
str.strip()

print(str)

Output:

+++Welcome python+++
