Pycharm – Improving and Writing Code ”; Previous Next PyCharm includes various standards for writing code with proper indentations valid for Python. This makes it interesting to improve the code standards and writing the complete code in PyCharm editor. Improving Code Completion Code completion in PyCharm is really unique. You can enhance it further using many other features. Note that the editor provides start and end of the code block. Consider a file named demo.py with the following code − message = ”GIEWIVrGMTLIVrHIQS” #encrypted message LETTERS = ”ABCDEFGHIJKLMNOPQRSTUVWXYZ” for key in range(len(LETTERS)): translated = ”” for symbol in message: if symbol in LETTERS: num = LETTERS.find(symbol) num = num – key if num < 0: num = num + len(LETTERS) translated = translated + LETTERS[num] else: translated = translated + symbol print(”Hacking key #%s: %s” % (key, translated)) The code is completed using the following construct − If you press Ctrl + spacebar while this popup is on the screen, you can see more code completion options − Intention Actions PyCharm includes intent specific actions and the shortcut key for the same is Alt+Enter. The most important example of intentions at work is using language injection in strings.

Adding a Data Source It is important to keep a note that PyCharm supports a wide variety of database connectivity. Step 1 Open the database tool window View -> Tool Windows -> Database> and open the dialog called Data Sources and Dialog. Now, select MySQL database for adding a new data source. Step 2 User should download the missing driver files to get proper connectivity with MySQL database. Step 3 Now, specify the configuration settings for connectivity to be achieved. Host − If you database server is on a different computer, replace localhost with the IP address of the server host, e.g. 172.20.240.163. Port − The default MySQL server port is 3306. If your server uses a different port, specify that port. User and Password − These are the required credentials. Step 4 Always make sure that database connectivity is successful through Test Connection feature. Testing the connection also involves creating test table through query and executing them. Once the execution is successful, you can drop the database. Print Page Previous Next Advertisements ”;
