Pycharm - Improving and Writing Code

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 −

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.
