Python: Convert a given heterogeneous list of scalars into a string

Python String: Exercise-91 with Solution

Write a Python program to convert a given heterogeneous list of scalars into a string.

Sample Solution:-

Python Code:

def heterogeneous_list_to_str(lst):
    result = ','.join(str(x) for x in lst)
    return result
h_data = ["Red", 100, -50, "green", "w,3,r", 12.12, False]
print("Original list:")
print(h_data)
print("\nConvert the heterogeneous list of scalars into a string:")
print(heterogeneous_list_to_str(h_data))

Sample Output:

Original list:
['Red', 100, -50, 'green', 'w,3,r', 12.12, False]

Convert the heterogeneous list of scalars into a string:
Red,100,-50,green,w,3,r,12.12,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")
