In this repository i will be writing about my progress in learning Python programming language..
my progress in the book "Python for Everybody" :
Chapter 1 :
In this chapter, I understood the components of the computer and how they work together
to execute my instructions "code" and how the processor works, and I also wrote my first
line of code "program"
print("Hello World")
and I also knew the difference between the compiler and the interpreter and the definition
of the program which is "a program is a set of statements or instructions for the computer
to do a certain task or a calculation" and I knew the difference between Syntax errors and
Logic errors and Semantic errors, and I also knew what Debugging means.
chapter 2 :
In this chapter, I learned about values and some data types, and I also learned about
variables and how to name them and assign them, and I also learned about Statements
Operators and operands and the order of operations and I learned about String operations
and string concatenation and how to get info from the user via the built-in function
"input", and I learned how to comment and how important comments are.
chapter 3 : in this chapter, I learned about boolean and comparisons and logical operators, and I also learned about conditional execution "if else and elif" and nested conditionals and short circuit, and I learned about try and except.
chapter 4 : in this chapter, I learned that functions are a named sequence of statements that performs computation and "returns" the result, which means it's a block of code that I can use as much as I want in the same program, and this block of code could be called by the functions name and could take as many values/variables "arguments" as I want it to take! and I learned about the built-in functions and how to make my own functions, I also learned about the flow of execution.
Chapter 5 : In this chapter, I learned how to update variables and I learned about while and for loops, and I learned about infinite loops and how to "break" a loop or to "continue" one.
chapter 6 : In this chapter, I learned about strings and that a string is a sequence of characters, and I learned about string Indexes and slicing by index, and I also learned that string is immutable, and I learned how to loop through strings, and I learned about the in operator and string comparison, and I learned about a function called "dir" which lists the "methods" available for an object, and another function called "help" that I can use to get some simple documentation on a method, and I learned about string parsing, and I learned about the "format" operator and how to use it.
chapter 7 : in this chapter, I learned how to open and read text files and how to search through them, and I also learned how to avoid the missing file errors using try and accept, and I learned how to open a file and write something in it and close it.
chapter 8: in this chapter, I learned about the lists and how to create them and that they are mutable, and I learned about lists methods and functions and I knew how similar strings and lists are and how to turn a list of characters into a string and how to turn a string into a list of characters, and I also learned about objects and values.
chapter 9: in this chapter, I learned about dictionaries and how to create them, and how to use them as a set of counters which is called "histogram", and I also learned about nested loops, and I also learned some advanced text parsing methods.
chapter 10: in this chapter, I learned about tuples and that they are immutable, and that a tuple is a sequence of values much like a list, the values stored in a tuple can be any type, and they are indexed by integers, tuples are also comparable and hashable so we can sort lists of them and use tuples as key values in Python dictionaries. syntactically, a tuple is a comma-separated list of values, although it is not necessary, it is common to enclose tuples in parentheses to help us quickly identify tuples when we look at Python code, and I learned about tuple assignment.
