Python: Determine the largest and smallest integers, longs, floats

Python Basic: Exercise-123 with Solution

Write a Python program to determine the largest and smallest integers, longs, floats.

Sample Solution:-

Python Code:

import sys
print("Float value information: ",sys.float_info)
print("\nInteger value information: ",sys.int_info)
print("\nMaximum size of an integer: ",sys.maxsize)

Sample Output:

Float value information: sys.float_info(max=1.7976931348623157e+308, max_exp=1024, max_10_exp=308, min=2.2250
738585072014e-308, min_exp=-1021, min_10_exp=-307, dig=15, mant_dig=53, epsilon=2.220446049250313e-16, radix=2
, rounds=1)                                                                                                   
                                                                                                              
Integer value information: sys.int_info(bits_per_digit=30, sizeof_digit=4)                                   
                                                                                                              
Maximum size of an integer: 9223372036854775807

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")
