#Lesson 1 :

import pandas as pd

import seaborn as sns #the first words you will be able to read in any code is the import bloc.

#when you start anything you need to prepare a frame and the tools.

#packages are the tools, the ide is the frame.

#Lesson 2

# A variable is usefull

# You will store informations.

ur_first_variable = "an unremarkable string"

#tada! It's stored!

#but be carefull. It will not be shown yet.

name = "Isidora" # Declaring variable name

favorite_number = 12 # Declaring variable favorite_number

#To see the variable in the console, you must call it. Using the print function!

print(name) # Using variable name for a variable can be a string

print(favorite_number) # Using variable number or a int/float.

#But a variable can be changed before it's called.

#then it will take the last known value.

str1 = "na"

str2 = "ba"

str1 = str2

print(str1)

#Lesson 3:

#Simple operations are possible in python:

#You can do computations (des calculs )

var1 = 7

var2 = 6

print (var1*var2)

# == tests that two values are equal.

# != tests that two values are not equal.

###### > and < test that greater than or less than, respectively.

##### >= and <= test greater than or equal to or less than or equal to, respectively.

#You can concatenate strings

var1 = "Gérard"

var2 = "Depardeux"

print (var1+" " + var2)

#Python has a number of built-in functions for strings. 68 in 2023 [source]: https://www.codecademy.com/resources/docs/python/built-in-functions

##### The 6 primitives of Turring ########

# Right: Move the Machine's head to the right of the current square.

# Left: Move the Machine's head to the left of the current square.

# Print: Print a symbol on the current square.

# Scan: Identify any symbols on the current square.

# Erase: Erase any symbols presented on the current square.

# Halt: Do nothing.

word = "learning"

print(word[1:5]) #Strings starts at 0 but a substring starts at 1 and ends at n+1

word = "steamer"

start = 1

end = 5

print(word[start:end])

text = 'bat ball'

# REPLACE 'ba' with 'ro'

replaced_text = text.replace('ba', 'ro')

print(replaced_text)

# Output: rot roll

######### REPLACE FCTION ########

forecast = "It will be rainy today"

new_forecast = forecast.replace("rainy", "sunny") #The REPLACE function returns a new string in which all instances of one substring are replaced with another substring.

print(forecast) # Original forecast

print(new_forecast) # New forecast

#LISTS / VARIABLES are useful in order to not type it every time. ie you store the informations in a variable so you can call it.

words = "red fish"

words.replace("red", "blue")

print(words)

print(words.replace("red", "blue"))

#in this example the variable words didn't saved the changes (just like in vidéo games)

form_letter = "Hello [Insert Name Here]. I'd like to personally thank you for your contribution."

# Run the replacement to insert Emily

form_letter = form_letter.replace("[Insert Name Here]", "Emily in Paris")

# Print the updated letter

print(form_letter)
