Problem

You are tasked with implementing a function that checks if a piece of code is production-ready based on two criteria: test coverage and performance metrics. The function should return True if the code meets the required test coverage of at least 80% and has a performance metric (execution time) less than a specified threshold. Otherwise, return False.

Input

• test_coverage: float: A float representing the percentage of code covered by tests (0 to 100).
• performance_metric: float: A float representing the execution time in seconds.
• threshold: float: A float representing the maximum acceptable execution time in seconds.

Output

• Returns a boolean indicating whether the code is production-ready.

Examples

Example 1:

Input: test_coverage = 85.0, performance_metric = 0.5, threshold = 1.0
Output: True

Explanation: Test coverage is above 80% and performance metric is below the threshold.

Example 2:

Input: test_coverage = 75.0, performance_metric = 0.4, threshold = 1.0
Output: False

Explanation: Test coverage is below 80%, hence not production-ready.

Constraints

• 0 <= test_coverage <= 100
• 0 <= performance_metric <= 10
• 0 < threshold <= 10
