Python: Move spaces to the front of a given string

Python String: Exercise-58 with Solution

Write a Python program to move spaces to the front of a given string.

Sample Solution:-

Python Code:

def move_Spaces_front(str1):
  noSpaces_char = [ch for ch in str1 if ch!=' ']
  spaces_char = len(str1) - len(noSpaces_char)
  result = ' '*spaces_char
  result = '"'+result + ''.join(noSpaces_char)+'"'
  return(result)

print(move_Spaces_front("w3resource .  com  "))
print(move_Spaces_front("   w3resource.com  "))

Sample Output:

"     w3resource.com"
"     w3resource.com"

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")
