Answer:
Here is a Python program that asks the user for a sentence and creates a new string based on the input that has all the spaces removed.
# Prompt the user for a sentence
sentence = input("Enter a sentence: ")
# Create a new string with all the spaces removed
no_spaces = sentence.replace(" ", "")
# Print the new string
print(f"New string: {no_spaces}")
Step-by-step explanation:
In this program, we first prompt the user for a sentence and store it in the sentence variable. We then use the replace method to create a new string with all the spaces removed. This method takes two arguments: the string to search for (in this case, a space), and the string to replace it with (in this case, an empty string).
Finally, we print the new string that has all the spaces removed. This program allows the user to input any sentence, and creates a new string based on that input that has all the spaces removed.
