❌بدترین کدهای پایتون چه ویژگی هایی دارند ؟
⬅️ به این موارد دقت کنید اگر اینجوری کدنویسی می کنید سعی کنید روشتون رو اصلاح کنید و کدهای زیبا و سریع تری بنویسید
1. Use incomprehensible names of variables
Call variables X, Y, A, Thing. Abstraction is the key to confusion
def f(x, y, z=None):
a = x * 2
b = y + a if z else y - a
c = [i for i in range(a) if i % 2]
return sum(c) + b
2. Sake maximum logic in one line
Complex thornar expressions and nested List CompreHance - all in one line.
result = [x if x > 0 else (y if y < 0 else z) for x in data if x or y and not z]
3. Use Eval () and Exec ()
It is slow, unsafe and stupid - but spectacular.
eval("d['" + key + "']")4. Reprint variables with different types
Let one variable be a line, and a number, and a list - a dynamic typification
value = "42"
value = int(value)
value = [value] * value
5. Use global variables
Change the condition of the application from anywhere. Especially from the inside of the functions.
counter = 0
def increment():
global counter
counter += 1
6. Use magic numbers and lines
Without explanation. Let colleagues guess why exactly 42 or "XYZ"
if user.role == "xyz" and user.level > 42:
access_granted()
7. Ignore style and indentation
No PEP8, no rules. Write as you want
def foo():print("start")
if True:
print("yes")
else:
print("no")8. Copy the code from Stack Overflow without delving
Ctrl+C is also a development
def complex_logic(x):
return (lambda y: (lambda z: z**2)(y + 1))(x)
9. Invent abstraction unnecessary
Instead of a simple function - classes, factories and strategies
class HandlerFactory:
def get_handler(self):
class Handler:
def handle(self, x): return x
return Handler()
10. Add dead code
Never remove - suddenly comes in handy. And let it be loaded into every launch
def legacy_feature():
print("This feature is deprecated")
return
# нигде не вызывается
11. Do not write the documentation
Comments only interfere. Whoever wants to figure it out
def a(x): return x+1
