input = input.lower()
return input[::-1] == input
print("\x1b[2J")
print("Father")

print "\n"
print("Dad")

Python – Test for Anagram
def is_anagram(input1, input2):
input1 = input1.lower()
input2 = input2.lower()
return sorted(input1) == sorted(input2)
print("\x1b[2J")
print("iceman cinema")
print(is_anagram("iceman", "cinema"))
print "\n"

Python – Minimize-Restore Window/Form
Minimize – root.wm_state(‘iconic’)
Restore – root.deiconify()
Python – Read Lines from Text File
Tested on a Mac, 10.12.6.
import os.path textFile = "/Users/Shared/TextFile.txt" doesFileExist=os.path.isfile(textFile) if doesFileExist == True: file = open(textFile,"r") lines=file.read().splitlines() global line1 global line2 line1 = lines[0] line2 = lines[1] file.close()
Notes
| Mode | Description |
|---|---|
| ‘r’ | This is the default mode. It Opens file for reading. |
| ‘w’ | This Mode Opens file for writing. If file does not exist, it creates a new file. If file exists it truncates the file. |
| ‘x’ | Creates a new file. If file already exists, the operation fails. |
| ‘a’ | Open file in append mode. If file does not exist, it creates a new file. |
| ‘t’ | This is the default mode. It opens in text mode. |
| ‘b’ | This opens in binary mode. |
| ‘+’ | This will open a file for reading and writing (updating) |
Python – Exit Window/Form
# function def quit(self): self.destroy() exit() # call function quit(root)
Python – Enable-Disable Button
button1.config(state=”active”)
button1.config(state=”disabled”)
Mac – Create a Daemon to Load App
Step 1 – Create a plist file. Save as something like com.TheAppName.plist
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>app.TheAppName</string> <key>ProgramArguments</key> <array> <string>/usr/bin/open</string> <string>/Applications/TheAppName.app</string> </array> <key>RunAtLoad</key> <true/> <key>KeepAlive</key> <false/> <key>LaunchOnlyOnce</key> <false/> <key>StartInterval</key> <integer>3600</integer><!-- seconds --> </dict> </plist>
Step 2 – Copy plist to /System/Library/LaunchDaemons/
Step 3 – Load the daemon
sudo launchctl load -w /System/Library/LaunchDaemons/com.TheAppName.plist
Step 4 – Log off & Log on to test
