Replace Blank Spaces with Hyphens using replace()

Now this program uses replace(), a pre-defined method of Python that takes mainly two arguments. The first argument's value gets replaced by the second argument's value. You can also provide the third argument as the number of times to replace the thing. But here, we only require two arguments to replace all blank spaces with hyphens.

print("Enter the String: ", end="")
str = input()

str = str.replace(' ', '_')
print("\nBlank spaces replaced with hyphens successfully!")
print("\nThe new string =", str)

Here is its sample run with user input, This is a Python program.:
