Python: Move all spaces to the front of a given string in single traversal
Python String: Exercise-71 with Solution
Write a Python program to move all spaces to the front of a given string in single traversal.
Sample Solution:-
Python Code:
def moveSpaces(str1):
no_spaces = [char for char in str1 if char!=' ']
space= len(str1) - len(no_spaces)
# Create string with spaces
result = ' '*space
return result + ''.join(no_spaces)
s1 = "Python Exercises"
print("Original String:\n",s1)
print("\nAfter moving all spaces to the front:")
print(moveSpaces(s1))
Sample Output:
Original String: Python Exercises After moving all spaces to the front: PythonExercises

What is the difference between Python's list methods append and extend?
append: Appends object at the end.
x = [1, 2, 3] x.append([4, 5]) print (x)
Output:
[1, 2, 3, [4, 5]]
extend: Extends list by appending elements from the iterable.
x = [1, 2, 3] x.extend([4, 5]) print (x)
Output:
[1, 2, 3, 4, 5]
