Output

Your tokenizer can be improved by ensuring that it correctly captures both numbers and operators in a more structured way. Additionally, the regular expression can be refined to handle whitespace properly and ensure that the operators are captured correctly without unnecessary grouping. Here’s a fixed version of your `Tokenizer` class:

        # Updated regex to capture numbers, operators, and parentheses
        self.tokens = re.findall(r'\d+|[+\-*/()]|sin|cos', input_str)
        self.position = 0

    def get_next_token(self):
        if self.position >= len(self.tokens):

        if self.position >= len(self.tokens):
            return None
        return self.tokens[self.position]
### Changes Made: 1. **Regular Expression**: The regex pattern was modified to simplify the capture of operators and parentheses by using a character class for operators `[+\-*/()]`. This ensures that each operator and parentheses is treated as a single token. 2. **Whitespace Handling**: By using the existing regex, it implicitly ignores whitespace, which is common in tokenization. This version maintains similarity to your original design while improving functionality and clarity.

Output

The tokenizer you've provided has a small issue in the regular expression pattern used to tokenize the input string. Specifically, the parentheses around the operators and functions should not be there, as they create a capturing group that returns only the matched operator or function instead of all tokens as intended. Here’s the corrected version of your `Tokenizer` class while keeping it as similar as possible:

### Changes Made: 1. Updated the regular expression to remove the capturing group `()` around the operators (`+`, `-`, `*`, `/`) and instead used square brackets `[]` to create a character class. This ensures that these tokens are included correctly in the resulting list of tokens. 2. Ensured that the code structure remains the same, retaining the overall functionality and design of your original tokenizer. This will now tokenize the input string correctly, capturing numbers, operators, trigonometric functions, and parentheses as intended.

Output

Your tokenizer class has a minor issue with the regular expression used in the `re.findall` method. The regex is designed to capture digits and operators, but the parentheses around the operators will create a tuple for the operators instead of returning them as individual tokens. This can cause issues when processing the tokens. Here's the corrected version of the `Tokenizer` class, which maintains the overall structure and functionality while fixing the regex issue:

### Changes Made: 1. **Regular Expression Adjustment**: Changed the regex pattern to `r'\d+|[+\-*/]|\b(?:sin|cos)\b|[()]'`. This allows the operators and functions to be captured correctly without creating tuples. - `\d+` captures digits. - `[+\-*/]` captures the arithmetic operators. - `\b(?:sin|cos)\b` captures the trigonometric functions `sin` and `cos` as whole words. - `[()]` captures parentheses. With these modifications, the `Tokenizer` class should now work as intended, processing the input string and tokenizing it correctly.

Output

The tokenizer you provided has a couple of issues that need to be addressed. The regular expression used in the `re.findall` method seems to be intended to capture both numbers and operators, but it has a small mistake that may lead to unexpected behavior. The parentheses in the regex are capturing groups, which may result in the tokens not being returned in the expected format. Here's an improved version of your `Tokenizer` class while keeping it as similar as possible:

### Key Improvements: 1. **Regex Update**: The regex now captures individual operators and parentheses correctly without unnecessary capturing groups. The updated regex `r'\d+|[+\-*/()]|sin|cos'` will match: - `\d+` for integers, - `[+\-*/()]` for individual operators and parentheses, - `sin` and `cos` for the trigonometric functions. 2. **Readability**: The code retains the overall structure and logic of your original implementation while improving the regex for better functionality. This should work correctly for a variety of mathematical expressions, allowing the tokenizer to properly identify numbers, operators, and function names.

### Changes Made: 1. **Import Statement**: Added `import re` at the top to ensure the regex functions are available. 2. **Regular Expression**: Updated the regex pattern used in `re.findall` to correctly match operators (`+`, `-`, `*`, `/`), parentheses (`(`, `)`), and functions (`sin`, `cos`) separately from numbers. The new pattern is `r'\d+|[+\-*/()]|sin|cos'`, which captures: - `\d+` for numbers - `[+\-*/()]` for operators and parentheses - `sin` and `cos` for the trigonometric functions This will ensure that the tokenizer works as intended.

assert answer == expected, f'Wrong answer; got {answer} instead of {expected}'
print('All tests passed')
And got the output: All tests passed

Substring Evaluation

Testing if the previous output contains the string All tests passed: True
