Python Math: Retrieve the current global context for all decimal

Python Math: Exercise-39 with Solution

Write a Python program to retrieve the current global context (public properties) for all decimal.

Sample Solution:-

Python Code:

import decimal
context = decimal.getcontext()
print('Emax     =', context.Emax)
print('Emin     =', context.Emin)
print('capitals =', context.capitals)
print('prec     =', context.prec)
print('rounding =', context.rounding)
print('flags    =')
for x, y in context.flags.items():
    print('  {}: {}'.format(x, y))
print('traps    =')
for x, y in context.traps.items():
    print('  {}: {}'.format(x, y))

Sample Output:

Emax     = 999999                                                                                             
Emin     = -999999                                                                                            
capitals = 1                                                                                                  
prec     = 28                                                                                                 
rounding = ROUND_HALF_EVEN                                                                                    
flags    =                                                                                                    
  <class 'decimal.InvalidOperation'>: False                                                                   
  <class 'decimal.FloatOperation'>: False   
  -----
 <class 'decimal.Rounded'>: False                                                                            
 <class 'decimal.Clamped'>: False

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")
