A requirements.txt must be present at the root of your application's repository to deploy.
To specify your python version, you also need a runtime.txt file - unless you are using the default Python runtime version.
Current default Python Runtime: Python 3.6.7
Alternatively, you can provide a setup.py file, or a Pipfile. Using Pipenv will generate runtime.txt based on python-version at build time.

}Error Strings
Error strings should not be capitalized (unless beginning with proper nouns or acronyms) or end with punctuation, since they are usually printed following other context. That is, use fmt.Errorf("something bad") not fmt.Errorf("Something bad"), so that log.Printf("Reading %s: %v", filename, err) formats without a spurious capital letter mid-message. This does not apply to logging, which is implicitly line-oriented and not combined inside other messages.
