There are a few different ways you can approach this problem. Here are a few possible solutions:1. Use a loop to iterate through each character in the string. If the character is a space, increment a counter variable. Finally, return the counter variable.```pythondef count_spaces(string): count = 0 for char in string: if char == ' ': count += 1 return count```2. Use the `count()` method of strings to count the number of occurrences of a specific character (in this case, a space).```pythondef count_spaces(string): return string.count(' ')```3. Use a list comprehension to create a list of all the spaces in the string, and then return the length of that list.```pythondef count_spaces(string): return len([char for char in string if char == ' '])```All of these solutions will give you the same result: the number of spaces in the input string.
