Which function is used to get user input in Python?

The function used to obtain user input in Python is input(). This built-in function prompts the user for input and returns it as a string. When called, it can display a message to the user (often referred to as a "prompt"), asking them to enter information. The input received can then be assigned to a variable for further processing within the program.

For example, using input("Please enter your name: ") will display the message "Please enter your name: ", and the user can type their name, which is subsequently stored as a string.

The other options do not serve the purpose of capturing user input in Python. The get() function is typically related to fetching data from a dictionary or similar structures, while read() is used for reading data from files. Similarly, receive() is not a recognized function in standard Python for user input. Thus, input() is the only correct choice for acquiring user input in a Python program.
