Wi-Fi and network connections in Intro to Computing - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to connect to a Wi-Fi network by specifying the network name.

Intro to Computing

connect_to_wifi(network_name=[1])

Drag options to blanks, or click blank then click option'

A192.168.1.1

Bpassword123

C"HomeNetwork"

💡 Hint

Common Mistakes

Using the password instead of the network name.

Using an IP address instead of the network name.

The network_name parameter should be the Wi-Fi network's name (SSID), such as "HomeNetwork".

Complete the code to check if the device is connected to Wi-Fi.

Intro to Computing

if connection_status == [1]:
    print("Connected to Wi-Fi")

Drag options to blanks, or click blank then click option'

ATrue

B"connected"

C"disconnected"

DFalse

💡 Hint

Common Mistakes

Using boolean True instead of the string "connected".

Using "disconnected" which means no connection.

The connection_status should be compared to the string "connected" to check if the device is connected to Wi-Fi.

3fill in blank

hard

Fix the error in the code to get the IP address assigned by the Wi-Fi router.

Intro to Computing

ip_address = get_ip_address([1])

Drag options to blanks, or click blank then click option'

Bwifi

CWiFi

D"wifi"

💡 Hint

Common Mistakes

Passing wifi without quotes causes a NameError.

Using capitalized WiFi without quotes is incorrect.

The interface name should be a string, so it must be in quotes like "wifi".

4fill in blank

hard

Fill both blanks to create a dictionary of Wi-Fi networks with their signal strengths greater than 50.

Intro to Computing

strong_networks = {network: [1] for network, strength in networks.items() if strength [2] 50}

Drag options to blanks, or click blank then click option'

Astrength

B>

C<

Dnetwork

💡 Hint

Common Mistakes

Using network as value instead of strength.

Using less than symbol which filters weak signals.

The dictionary should map each network to its strength if the strength is greater than 50.

5fill in blank

hard

Fill all three blanks to create a dictionary of Wi-Fi networks with names in uppercase and signal strength above 70.

Intro to Computing

filtered_networks = [1]: [2] for [3], strength in networks.items() if strength > 70}

Drag options to blanks, or click blank then click option'

Anetwork.upper()

Bstrength

Cnetwork

Dnet

💡 Hint

Common Mistakes

Using 'net' instead of 'network' as loop variable.

Not converting network names to uppercase.

The keys are the network names in uppercase (network.upper()), the values are the signal strengths, and the loop variable is network.
