Question
Count spaces, periods, or commas in python
Write a program that asks the user for a line of text and counts how many spaces, periods, or commas the text contains using the specified
output format.
Examples
If the input is:
Hello, world.
the output is:
There are 1 space, 1 period, and 1 comma.
If the input is:
Listen, Mr. Jones, calm down.
the output is:
There are 4 spaces, 2 periods, and 2 commas.
Hints
• Review Figure 4.5.2 to see how to iterate over characters.
• Go over the string, character by character, and increment the counters for the requested characters.
• You will need a separate counter for every symbol that you are counting.
• Do not forget - initially, we do not have any characters counted, so the counter should be 0.
• You will need a separate check for each symbol to know whether to print its counter with a singular or a plural noun
