7 Hidden Python Function Tricks That Clean Your Code Instantly

 

1. Default argument makes function flexible

def greet(name="User"):
    return f"Hello,{name}"
print(greet())
print(greet("Alice"))

#source code --> clcoding.com 

Output:

Hello,User
Hello,Alice

2. Return multiple values at once
def stats(a,b):
    return a+b,a*b
s,m=stats(4,5)
print(s,m)

#source code --> clcoding.com 
Output:
9 20

3. Use *args for unlimited arguments
def add_all(*nums):
    return sum(nums)

print(add_all(1,2,3,4))
#source code --> clcoding.com 
Output:
10

4. Use *kwargs for flexible name argument
def show_info(**details):
    return details

print(show_info(name="Alice",age=25))

#source code --> clcoding.com 
Output:
{'name': 'Alice', 'age': 25}

5. Lambda function for one line logic
multiply=lambda x,y:x*y
print(multiply(3,4))
#source code --> clcoding.com 
Output:
12

6. Use docstring to describe your function
def area(r):
    """Returns area of a circle"""
    return 3.14 *r*r
print(area.__doc__)
#source code --> clcoding.com 
Output:
Returns area of a circle

7. Eary return makes code cleaner

def check(num):
    if num <0:
        return "Negative"
    return "Positive is zero"

print(check(-5))
print(check(3))
#source code --> clcoding.com 
Output:

Positive is zero
