The application relates to a code translation method and device, electronic equipment and a storage medium. The method comprises the following steps: determining whether a source function needs to retrieve assistance, determining the source function and a corresponding similar function as input functions if the source function needs to retrieve assistance; otherwise, determining the source function as an input function; collecting context information related to the input function from a source warehouse and a target warehouse; generating an initial target function according to the input function and the context information; determining whether a test execution result is a test pass, and determining the initial target function as a target function if the test execution result is the test pass; otherwise, performing an iterative reflection repair operation until the test pass or a maximum iteration number is reached. A closed-loop mechanism of 'generation-test-reflection-retrieval-correction' is established, the error root cause is deeply analyzed, the context information is reacquired according to the error by calling a tool, accurate positioning and effective repair of the error code are realized, and the test pass rate of code translation is greatly improved.
