What does pycharm mean when running in parallel?
The parallel running function in PyCharm allows running code blocks concurrently, improving development and testing efficiency. By enabling this feature and setting the number of processes, you can: Speed up the development and debugging process. Reduce test suite run time. Take full advantage of multi-core processors. Simplify the structure and maintenance of complex code.
Parallel running in PyCharm
PyCharm is a powerful Python integrated development environment (IDE). This includes a feature called "Parallel Run". It allows you to split your code into multiple chunks that run concurrently, making development and testing more efficient.
How to Enable Parallel Running
Enabling parallel running in PyCharm is very simple:
- Open PyCharm and load your project.
- Navigate to the Run menu.
- Click on the "Edit Configuration" option.
- In the "Run/Debug Configuration" dialog box, select "Python" as the runner type.
- In the "Parallel" tab, check the "Enable parallel runs" checkbox.
- Set the number of processes you want to run in parallel.
Benefits of parallel running
Using parallel running provides the following benefits:
- Increased development speed: By running multiple parts of your code simultaneously, you can speed up the development and debugging process.
- Improve testing efficiency: Parallelizing your test suites can significantly reduce run times, allowing you to identify bugs faster.
- Take full advantage of multi-core processors: Modern computers often have multiple cores, and running in parallel can take advantage of these cores to improve performance.
- Simplify complex code: Splitting code into chunks that run in parallel simplifies the structure and maintenance of complex applications.
Usage Example
To use parallel execution, you can use ThreadPoolExecutor from the concurrent.futures module kind. Here is an example that creates a thread pool and uses it to run three functions in parallel:
from concurrent.futures import ThreadPoolExecutor
def task(n):
return n * n
with ThreadPoolExecutor() as executor:
results = executor.map(task, range(1, 4))
for result in results:
print(result) In this example, ThreadPoolExecutor uses three threads to execute the task in parallel function and store the results in the results list.
Notes
When using parallel running, you need to consider the following considerations:
- Shared resources: Parallel When resources are shared between running blocks, synchronization may be required to avoid race conditions.
- Debugging Difficulty: Debugging parallel code can be more complex than debugging code that runs sequentially.
- Potential Overhead: Creating and managing threads for parallel runs may introduce some overhead, especially for small tasks.

python asyncio queue example
Aug 21, 2025 am 02:13 AM
asyncio.Queue is a queue tool for secure communication between asynchronous tasks. 1. The producer adds data through awaitqueue.put(item), and the consumer uses awaitqueue.get() to obtain data; 2. For each item you process, you need to call queue.task_done() to wait for queue.join() to complete all tasks; 3. Use None as the end signal to notify the consumer to stop; 4. When multiple consumers, multiple end signals need to be sent or all tasks have been processed before canceling the task; 5. The queue supports setting maxsize limit capacity, put and get operations automatically suspend and do not block the event loop, and the program finally passes Canc

How to use regular expressions with the re module in Python?
Aug 22, 2025 am 07:07 AM
Regular expressions are implemented in Python through the re module for searching, matching and manipulating strings. 1. Use re.search() to find the first match in the entire string, re.match() only matches at the beginning of the string; 2. Use brackets() to capture the matching subgroups, which can be named to improve readability; 3. re.findall() returns all non-overlapping matches, and re.finditer() returns the iterator of the matching object; 4. re.sub() replaces the matching text and supports dynamic function replacement; 5. Common patterns include \d, \w, \s, etc., you can use re.IGNORECASE, re.MULTILINE, re.DOTALL, re

How to debug a remote Python application in VSCode
Aug 30, 2025 am 06:17 AM
To debug a remote Python application, you need to use debugpy and configure port forwarding and path mapping: First, install debugpy on the remote machine and modify the code to listen to port 5678, forward the remote port to the local area through the SSH tunnel, then configure "AttachtoRemotePython" in VSCode's launch.json and correctly set the localRoot and remoteRoot path mappings. Finally, start the application and connect to the debugger to realize remote breakpoint debugging, variable checking and code stepping. The entire process depends on debugpy, secure port forwarding and precise path matching.
