Pycharm - Improving and Writing Code

PyCharm 包含各种编写代码的标准，其中适用于 Python 的缩进有效。这使得在 PyCharm 编辑器中提高代码标准和编写完整代码变得很有意思。

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

PyCharm 中的代码自动完成非常独特。您可以使用许多其他功能进一步增强它。请注意，编辑器提供了代码块的开始和结束。考虑一个名为 demo.py 的文件，其中包含以下代码 −

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))

代码使用以下构造完成 −
