One-Dimensional Arrays in Python

How do you create a one-dimensional array in Python?

• You can use the 'dictionary' module

• You can use the 'tuple' module

• You can use the 'set' module

• You can use the 'array' module or simply use a list.

What is the syntax for accessing elements in a one-dimensional array in Python?

• array_name{index}

• array_name[index]

• array_name.at(index)

• array_name(index)

How can you modify an element at a specific index in a one-dimensional array in Python?

• By creating a new array with the modified element and replacing the original array

• By using a loop to iterate through the array and modify the element at the specific index

• By using the index to access the element and then assigning a new value to it.

• By converting the array to a string and then modifying the element at the specific index

What is the process of iterating through a one-dimensional array in Python?

• Use a while loop

• Use a switch statement

• Use a do-while loop

• Use a for loop

How do you find the length of a one-dimensional array in Python?

• len(array_name)

• array_name.count()

• array_name.size()

• array_name.length()

Explain the process of concatenating two one-dimensional arrays in Python.

• You can use the numpy library's subtract function

• You can use the numpy library's concatenate function or the built-in extend method for lists.

• You can use the built-in append method for lists

• You can use the pandas library's merge function

Write a Python code to create a one-dimensional array with elements [1, 2, 3, 4, 5].

• arr = np.array(1, 2, 3, 4, 5)

• import numpy as np arr = np.array([1, 2, 3, 4, 5])

• arr = array(1, 2, 3, 4, 5)

• arr = [1, 2, 3, 4, 5]

What is the value at index 3 in the one-dimensional array [10, 20, 30, 40, 50]?

• 30

• 10

• 50

• 40

How would you change the value at index 2 in the array [5, 7, 9, 11, 13] to 10?

• arr[2] = 10

• arr[1] = 10

• arr[3] = 10

• arr[2] = 5

Write a Python code to iterate through the elements of the array [6, 8, 10, 12, 14].

• for i in [6, 8, 10, 12, 14]:

• for i in range(6, 14):

• for num in [6, 8, 10, 12, 14]:

• for x in [6, 8, 10, 12, 14]:
