Cursed Python

I discovered the wonders of exec and decided to find more cursed python fuctionality.

Switch Statements

Use an array to run the code of the switch statement and the index is what the value equals.

print("Enter 1-5")
key = int(input())-1

arr = ["v=3", "v=5", "print('hahaha')\nv=13", "v=4", "v=19"]
exec(arr[key])
print("V: " + str(v))

One Liner

exec('''print("Enter 1-5");key = int(input())-1;arr = ["v=3", "v=5", "print('hahaha');v=13", "v=4", "v=19"];exec(arr[key]);print("V: " + str(v))''')

Define Methods in Dictionaries

Defines a method with parameters within a dictionary

print("Enter factorial")
init_val = int(input())
methods = {
    'factorial': "def factorial(x):\n    if x == 1:\n      return 1\n    else:\n      return (x*factorial(x-1))\n\n\nvalue = factorial(init_val)\nprint(value)"
}

exec(methods['factorial'])

One Liner

exec('''print("Enter factorial")\ninit_val = int(input())\nmethods = {'factorial': "def factorial(x):\\n    if x == 1:\\n      return 1\\n    else:\\n      return (x*factorial(x-1))\\n\\n\\nvalue = factorial(init_val)\\nprint(value)"}\nexec(methods['factorial'])''')
