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")
