Exec Input Syntax Claim Fact Checked
“Is this wrote correctly exec(input() then the English just goes in here () after input and exec executes that as if it was code”
Summary
In Python the correct form is `exec(input())`, which reads a string from the user and executes it as Python code. The phrasing “exec(input() then the English just goes in here () after input” is not valid Python syntax, and the input must be valid Python statements, not arbitrary English.

It takes either a string or an object as the first and necessary parameter for the dynamic execution of the input. If a string is given as an input, then it is parsed as a suite of Python code.

In all cases, the code that’s executed is expected to be valid as file input (see the section File input in the Reference Manual). Be aware that the nonlocal, yield, and return statements may not be used outside of function definitions even within the context of code passed to the exec() function.
- Command Injection | OWASP Foundation
For example (Java): Rather than use Runtime.exec() to issue a ‘mail’ command, use the available Java API located at javax.mail.*. If no such available API exists, the developer should scrub all input for malicious characters. Implementing a positive security model would be most efficient.

In this example, you use a triple-quoted string to provide the input to exec(). Note that this string looks like any regular piece of Python code. It uses appropriate indentation, naming style, and formatting.
- How to Use exec() in Python - Everything You Need to Know - DEV Community
A new line character (\n) is defined to make the exec() function understand our single-line string-based code as a multiline set of Python statements. In Python, we frequently use triple quotes to comment on or document our code. However, in this case, we'll use it to generate string-based input that looks and behaves exactly like normal Python code. The code we write within triple quotes must be properly indented and formatted, just like normal Python code. See the example ...
