    print(x,y)
    x, y = y, x
    print(x,y)
IPS()

Case of Letters:

def letters():
    s = "sTeRn"
    print(s.lower())
    print(s.upper())
letters()

Spelling a word:

import stern
def listletters():
    s = "stern"
    print(list(s))
listletters()

Unique or NOT unique list:

import stern
def unique():
    x = [1,9,9,1]
    if(len(x) == len(set(x))):
        print("The list is unique")
    else:
        print("The list is NOT unique")
unique()

For Else construct:

import stern
def difference():
    first = [1,2,3]
    second = [1,2,3]
    print(first == second)
    print(first is second)
    third = first
    print(first is third)
difference()

Removing duplicates:

import stern
def duplicates():
    list_numbers = [20,22,24,26,28,28,20,30,24]
    print('Before:',list_numbers)
    list_numbers = list(set(list_numbers))
    print('After:',list_numbers)
duplicates()

Exchanging Values with Tuples:

import stern
def EVT():
    a, b = 1, 2

    a, b = b, a
    print(a, b)
EVT()

    a = ["stern", "-", "is good", "module."]
    print(" ".join(a))
StringConcatenation()

Dictionary and set generators:

import stern
def DictionaryGenerators():
    S = {i**2 for i in range(10)}
    D = {i: i**2 for i in range(10)}
    print(S)
    print(D)
DictionaryGenerators()

Output with print:

import stern
def Output():
    for part in ["stern ", "is ", "good", "\n"]:

Output()

Finding the Most Duplicate Items in a List:

import stern
def FMDIL():
    a = [1, 2, 3, 1, 2, 3, 2, 2, 4, 5, 1]
    print(max(set(a), key=a.count))
FMDIL()

Kwargs:

import stern
def Kwargs():
    dictionary = {"a": 1, "b": 2}
    def some_function(a, b):

Building From Source

If you want to use features that are currently in development, or you want to contribute to stern, you will need to build stern locally from its source code, rather than pip installing it.

Installing from source is fairly automated. The most work will involve compiling and installing all the stern dependencies. Once that is done, run the setup.py script which will attempt to auto-configure, build, and install stern.
