Python Coding Challange - Question With Answer(01250325)

 

Explanation:

1. import array as arr

   • This imports the built-in array module with an alias arr.

2. numbers = arr.array('f', [8, 's'])

   • 'f' specifies that the array should contain floating-point numbers (float type).

   • However, the second element in the list ('s') is a string, which is not allowed in a float array.

   • This will cause a TypeError at runtime.

Expected Error:

TypeError: must be real number, not str

Corrected Code:

If you want a float array, all elements must be floating-point numbers:

import array as arr

numbers = arr.array('f', [8.0, 5.5]) # Use only float values
print(len(numbers)) # Output: 2

Python Coding Challange - Question With Answer(01230325)

 

Explanation of the Code:

1. Creating an Empty Dictionary:

   
   personsAges = dict()

   • This initializes an empty dictionary named personsAges.

2. Adding Key-Value Pairs:

   
   personsAges["Smith"] = 21
   personsAges["Mike"] = 27

   • Here, two key-value pairs are added to the dictionary:

     • "Smith" as the key with 21 as the value.

     • "Mike" as the key with 27 as the value.

3. Looping Through the Dictionary:

   
   for key, value in personsAges.items():
       print(key)

   • The .items() method retrieves key-value pairs from the dictionary.

   • The for loop iterates over these pairs.

   • key represents the names ("Smith", "Mike"), and value represents the ages (21, 27).

   • print(key) prints only the keys.

Expected Output:

Smith
Mike

Since only the key is printed, we get the names "Smith" and "Mike" as output.

Python Coding Challange - Question With Answer(01210325)

 

Key Points:

1. Local Scope of name

   • The variable name is defined inside the function set_name().
   • This means name exists only within the function's scope and cannot be accessed outside.

2. Function Execution (set_name())

   • The function runs and assigns 'Python' to name, but since name is local, it is lost after the function finishes execution.

3. Error in print(name)

   • The print(name) statement is outside the function and cannot access name because name only exists inside set_name().
   • Result: Python will throw a NameError: name 'name' is not defined.

How to Fix It?

If you want name to be accessible outside the function, you can:

Solution 1: Return the value

def set_name():
    return 'Python'

name = set_name() # Store the returned value in a variable
print(name) # Output: Python

---

Solution 2: Use a Global Variable (Not Recommended)

def set_name():
    global name # Declare 'name' as global
    name = 'Python' 
set_name() 
print(name) # Output: Python

• This works but using global is not recommended unless absolutely necessary, as it can lead to unexpected behavior.
•
