pylib-general 0.2.2

general python features that may come in handy at some point.

PyLib - General

This is a package that will be updated whenever I get an idea that I like and write it.

So far, I have:

• Properties
• Num
• Text
• Exceptions

Properties

This can be used like:

from pylib_general import properties import pylib_general.properties as properties

This loads the Property class, which can be used like:

varname = properties.Property()

The property class's functions are:

• varname.add(name, val)

name being the name of the new value (cannot contain spaces), and val being the value.

• varname.remove(name) name being the name of the value to remove

• varname.get(name) returns the value of name

The difference between Property and other sets is that you can get a property in a much easier way:

varname.attr

Obviously, you can also get a value through varname.get(name) but you could also do varname.name

Ex:

varname = Property().add("somenamenotcontainingnumbersorspaces", "12233090")
print(varname.somenamenotcontainingnumbersorspaces)

prints 12233090

A hidden way to get values is varname.__dict__["name"] (Not preferable)

calling that, varname.attr, del varname.attr, or varname.attr = val will call the get, remove, and add functions respectively.

Num

This can be used like:

from pylib_general import num import pylib_general.num as num

This loads the number functions, which are:

• num.factorial(n)

Where n is the number you want to factorial, returns n!

• num.sig(n)

Where n is the number you want to sigma, returns n + (n-1) + (n-2) ...

• num.pow(n, p)

Where n is the number you want to raise to the power of p. Returns n^p (python syntax: n**p)

• num.incr(n)

Where n is the number to increment by 1. Returns n + 1

• num.decr(n)

Where n is the number to decrement by 1. Returns n - 1

• num.mod(n, d)

Where n is the number to modulo with d. Returns n % d

• num.get_fibo(terms)

Where terms is the number of terms of the Fibonacci sequence you want to get. Returns array. Special usage: get_fib(3)[2] will return 1, same as _recur_fib(2) (preferably not used)

• num.pi

Equals 22/7

Text

This can be used like:

from pylib_general import text import pylib_general.text as text

• text.checkstr(ost)

Checks if ost is a string or not. returns True or False.

• text.rev(ost)

Returns the reverse of the string ost

• text.ascii_convert(ost)

Takes ost and converts it's characters into their ascii codes separated with hyphens (dashes). Returns string. Ex: text.ascii_convert("ccC") returns "99-99-67"

• text.caesarcipher(ost, key=1)

Takes ost and shifts the characters by a key, giving the Caesar Ciphered version of it as a string. Ex: text.caesarcipher("ccC") returns "ddD"

• text.weirdcase(ost)

Takes ost and makes every other letter uppercase. Ex: text.weirdcase("ccced") returns "CcCeD" Note: if instead of "CcCeD" you want "cCcEd," you can use text.weircase("ccced").swapcase()

• text.encode(ost, key=1)

Ah, here is the masterpiece of the text module: encode! It takes ost and reverses the the ascii version of the weirdcase of the caesarcipher of ost. The code for the return value is rev(ascii_convert(weirdcase(caesarcipher(ost, key)))) Ex: text.encode("ccC") returns "86-001-86"

• text.checkpalindrome(ost)

Takes ost and checks if it is a palindrome.

Exceptions

This can be used like:

from pylib_general import exceptions import pylib_general.exceptions as exceptions

• exceptions.Error

Literally just an exception, except under a different name.

• exceptions.NumTooLowError(value, message="Value was too low.")

when raised, shows exceptions.NumTooLowError: 112: Value was too low. (assuming the value parameter was 112)

• exceptions.NumTooHighError(value, message="Value was too high.")

when raised, shows exceptions.NumTooHighError: 112: Value was too high (assuming the value parameter is 112)

• exceptions.NumNotInRangeError(nrange, value, message="Value not in range ")

when raised correctly, shows exceptions.NumNotInRangeError: 112: Value not in range (2, 99) (assuming the nrange passed was [2, 99] and the value passed was 112)
