Python Tuple Data

A tuple is a collection of data that is ordered and unchangeable. In Python, tuples are written with round brackets. For example, my_tuple = (1, 2, 3) is a tuple with three elements. You can access the elements of a tuple by using indexing or slicing. For example, my_tuple[0] returns 1 and my_tuple[1:3] returns (2, 3). You can also use some methods on tuples such as count() and index(). For example, my_tuple.count(2) returns how many times 2 appears in the tuple and my_tuple.index(3) returns the position of 3 in the tuple. Tuples are useful for storing data that does not change and for packing and unpacking values.

Here are some examples of Python code using tuples:

# Creating a tuple
fruits = ("apple", "banana", "cherry")

# Accessing a tuple element
print(fruits[1]) # prints banana 

# Slicing a tuple
print(fruits[-2:]) # prints ("banana", "cherry") 

# Looping through a tuple
for fruit in fruits:
    print(fruit) 

# Checking if an element is in a tuple
if "apple" in fruits:
    print("Yes") 

# Finding the length of a tuple
print(len(fruits)) # prints 3 

# Counting how many times an element appears in a tuple
print(fruits.count("apple")) # prints 1 

# Finding the position of an element in a tuple
print(fruits.index("cherry")) # prints 2

# Packing and unpacking tuples
a = 10
b = 20
c = (a, b) # packing
x, y = c # unpacking
print(x) # prints 10
print(y) # prints 20

Python chr() Built in Function

The Python chr() function is used to get a string representing a character that corresponds to a Unicode code integer. For example, chr(97) returns the string 'a'. This function takes an integer argument and throws an error if it exceeds the range of 0 to 1,114,111. Here are some examples of using the chr() function in Python: # Get the character for ASCII code 65 print(chr(65)) # Output: A # Get the character for Unicode code point 1200 print(chr(1200)) # Output: Ұ # Get the characters for a list of integers codes = [71, 101, 101, 107, 115] chars = [chr(code) for code in codes] print(''.join(chars)) # Output: Geeks To print ‘Hello World’ using chr() , you can write: print(chr(72) + chr(101) + chr(108) + chr(108) + chr(111) + chr(32) + chr(87) + chr(111) + chr(114) + chr(108) + chr(100)) To print a list of all uppercase letters using chr() , you can write: letters = [] for i in range(65, 91):     letters.append(chr(i)) print(letters) To print a smiley face emoji...

Stock Market Predictions with LSTM in Python

Stock Market Predictions with LSTM in Python is a tutorial that shows how to create a three-layer LSTM model using TensorFlow and Keras. Here is a snippet of how to define the model: # Define the LSTM model model = Sequential() model.add(LSTM(units=50, return_sequences=True, input_shape=(x_train.shape[1], 1))) model.add(LSTM(units=50)) model.add(Dense(1))   # Compile and fit the model model.compile(loss='mean_squared_error', optimizer='adam') model.fit(x_train, y_train, epochs=25, batch_size=32) Stock Market Analysis + Prediction using LSTM is a notebook that shows how to load stock market data from Yahoo finance using yfinance module, how to explore and visualize time-series data using pandas, matplotlib, and seaborn, how to measure the correlation between stocks, how to measure the risk of investing in a particular stock, and how to use LSTM (Long Short-Term Memory) model for predicting future stock prices. Here is a snippet of how to create and train an LSTM model f...

Collections In Python

Python collections are data structures that store multiple items of the same or different types. There are four built-in collection types in Python: list, tuple, set and dictionary. Additionally, there is a module called collections that provides more specialized collection types such as Counter, OrderedDict, defaultdict and namedtuple. Here are some examples of using Python collections: List: A list is a collection that is ordered and changeable. The Python lists are defined with square brackets. # Create a list of fruits fruits = ["apple", "banana", "cherry"] # Print the list print(fruits) # Output: ['apple', 'banana', 'cherry'] Tuple: A tuple is a collection that is ordered and unchangeable. The Python tuples are written with round brackets. # Create a tuple of colors colors = ("red", "green", "blue") # Print the tuple print(colors) # Output: ('red', 'green', 'blue') Set: A...

Python Count Occurrence Of Elements

There are several ways to count the occurrence of elements in a Python list. One way is to use the list.count() method which takes an element as an argument and returns the number of times it appears in the list. For example: a = [1, 2, 3, 4, 1, 2, 1] b = a.count(1) # b is 3 c = a.count(5) # c is 0 Another way is to use a loop and a counter variable to iterate over the list and increment the counter whenever the element is found. For example: a = [1, 2, 3, 4, 1, 2, 1] x = 1 count = 0 for ele in a:     if ele == x:         count += 1 # count is 3  A third way is to use a dictionary or a defaultdict to store the elements as keys and their counts as values. For example: from collections import defaultdict a = [1, 2, 3, 4, 1 ,2 ,1] occurrence = defaultdict(lambda:0) for ele in a:     occurrence[ele] += 1 # occurrence is {1:3 ,2:2 ,3:1 ,4:1} It is good to have an idea of the number of times elements occurred in your data...

Python One Liner Functions

Python one-liner functions are functions that can be written in a single line of code. They are often used to perform simple tasks or expressions without defining a named function. One way to create a one-liner function is to use the lambda keyword which creates an anonymous function that takes some arguments and returns a value. For example: # A lambda function that returns the square of a number square = lambda x: x**2 print(square(5)) # 25 # A lambda function that checks if a number is even is_even = lambda x: x%2 == 0 print(is_even(4)) # True Another way to create a one-liner function is to use the def keyword with a colon and an expression after it. This creates a named function that returns the value of the expression. For example: # A one-liner function that returns the sum of two numbers def add(x, y): return x + y print(add(3, 4)) # 7 # A one-liner function that reverses a string def reverse(s): return s[::-1] print(reverse("hello")) # olleh Python offers a one-l...
