+For comparison, here is the same code with no comments:
+<code:python | download>
+import network
+import time
+wlan = network.WLAN(network.STA_IF)
+wlan.active(True)
+ssid = "YOUR-SSID"
+password = "YOUR-WIFI-PASSWORD"
+wlan.connect(ssid, password)

+==== Running the Code ====
+\\
+I have called my script wifi-connect.py because if I run it at boot, I may not see the IP Address, I need to test this idea.
+\\
+\\
+When I run my wifi-connect.py from Thonny, this is what I see:
+\\
+\\
+{{ :wifi-connect-code-001.png?800 |}}
+\\
+At the bottom of the Thonny IDE we see the following:
+\\
+  * Connected!
+  * ('10.194.1.205', '255.255.255.0', '10.194.1.1', '10.194.1.1')
+This tells us that we were successfully connected and that we have the following IP details:
+  * IP Address - 10.194.1.205
+  * Subnet - 255.255.255.0
+  * Gateway - 10.194.1.1
+  * DNS - 10.194.1.1
+This works very well, but unfortunately you need to be connected to an IDE to see the output of the IP Address details.

+==== Wifi Connect with LCD ====
+\\
+If you have completed the wiki page [[using_pico_with_ssd1306_based_lcd|Using Pico with SSD1306 based LCD]] and you still have your LCD, then you can use this following code to:
+  * Connect to the Wifi
+  * Print IP to LCD
+Download the code below and save it to your Pico as lcd-test-wifi.py
+<code:python | download>
+from machine import Pin, I2C
+import ssd1306
+import network
+import time
+#------------- wufi connect --------------------
+wlan = network.WLAN(network.STA_IF)
+wlan.active(True)
+ssid = "YOUR-SSID"
+password = "YOUR-WIFI-PASSWORD"
+wlan.connect(ssid, password)
+while not wlan.isconnected():
+    print("Connecting...")
+    time.sleep(0.5)
+#Print your IP address
+print("Connected!")
+print(wlan.ifconfig())
+#------------------------------------------------
+#-------------- LCD Show ------------------------
+# Your wiring: SDA=GP4, SCL=GP5 → I2C0
+i2c = I2C(0, scl=Pin(5), sda=Pin(4), freq=200000)
+lcd = ssd1306.SSD1306_I2C(128, 64, i2c)
+lcd.fill(0)
+lcd.text("Yo Tuesday Club!", 0, 0)
+lcd.text("SSD1306 LCD", 0, 16)
+lcd.text("Address 0x3C", 0, 32)
+#converts IP information (its a tuple, kinda like an array, into a string)
+ip = wlan.ifconfig()[0]   # first item = IP address
+lcd.text("IP: " + ip, 0, 48)
+lcd.show()
+#------------------------------------------------
+time.sleep(300)
+lcd.fill(0)
+lcd.show()
+</code>
+If this has worked then you should see something similar to below.
+\\
+\\
+{{ :wifi-connect-lcd.png?800 |}}
+\\
+Here we can see the last line on the LCD is my Pico IP Address
