Python Coding Challange - Question with Answer (01030925)

 

Let’s carefully walk through this step by step.

---

Code:

def func(a, b, c=5):
    print(a, b, c)
func(1, c=10, b=2)

---

Step 1: Function definition

def func(a, b, c=5): 
    print(a, b, c)

• The function func takes three parameters:

  • a → required

  • b → required

  • c → optional (default value 5)

If you don’t pass c, it will automatically be 5.

---

Step 2: Function call

func(1, c=10, b=2)

• 1 → goes to a (first positional argument).

• b=2 → keyword argument, so b = 2.

• c=10 → keyword argument, so it overrides the default c=5.

---

Step 3: Values inside the function

Now inside func:

a = 1 

b = 2 

c = 10

---

Step 4: Output

The print statement runs:

print(a, b, c) # 1 2 10

✅ Final output:

1 2 10

---

⚡ Key Takeaway:

• Positional arguments come first.

• Keyword arguments can be passed in any order.

• Defaults are only used when you don’t override them.
