1. What is Python Syntax?<\/h2>\n

Syntax<\/strong> means the rules of writing Python code.<\/p>\n

If you follow the rules, Python understands you.
If you break the rules, Python shows an error.<\/p>\n

Good news \ud83d\ude0a
Python syntax is simple and clean<\/strong>.<\/p>\n

2. Python Uses Indentation (Spaces)<\/h2>\n

Python does not use { }<\/code> like other languages.
It uses spaces (indentation)<\/strong> to group code.<\/p>\n

\u2705 Correct Example<\/h3>\n
\n
\n
\n
<\/div>\n<\/div>\n<\/div>\n
if<\/span> 10<\/span> > 5<\/span>:
\nprint<\/span>(\"10 is greater than 5\"<\/span>)
\n<\/code><\/div>\n<\/div>\n

Here:<\/p>\n

    \n
  • \n

    :<\/code> means a new block starts<\/p>\n<\/li>\n

  • \n

    The space before print<\/code> is very important<\/p>\n<\/li>\n<\/ul>\n

    \u274c Wrong Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    if<\/span> 10<\/span> > 5<\/span>:
    \nprint<\/span>(\"10 is greater than 5\"<\/span>)
    \n<\/code><\/div>\n<\/div>\n

    This gives an IndentationError<\/strong>.<\/p>\n

    \ud83d\udc49 Always use 4 spaces<\/strong>.<\/p>\n

    3. Python is Case-Sensitive<\/h2>\n

    Capital letters and small letters are different.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    name = \"Ravi\"<\/span>
    \nName = \"Amit\"<\/span><\/code><\/code>print<\/span>(name)
    \nprint<\/span>(Name)<\/div>\n<\/div>\n

    Both are different variables<\/strong>.<\/p>\n

    4. Writing Python Statements<\/h2>\n

    Usually, one line = one statement.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    print<\/span>(\"Hello\"<\/span>)
    \nprint<\/span>(\"Python\"<\/span>)
    \n<\/code><\/div>\n<\/div>\n

    Python does not need ;<\/code><\/p>\n

    5. Python Comments<\/h2>\n

    Comments are notes for humans.
    Python ignores comments.<\/p>\n

    Single-Line Comment<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    # This prints a message<\/span>
    \nprint<\/span>(\"Hello Python\"<\/span>)
    \n<\/code><\/div>\n<\/div>\n

    Multi-Line Comment<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    \"\"\"
    \nThis program shows
    \nPython syntax
    \n\"\"\"<\/span>
    \nprint<\/span>(\"Welcome\"<\/span>)
    \n<\/code><\/div>\n<\/div>\n

    6. Python Variables Syntax<\/h2>\n

    Variables store values.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    age = 25<\/span>
    \nname = \"Suman\"<\/span>
    \nprice = 99.50<\/span>
    \n<\/code><\/div>\n<\/div>\n

    Python automatically understands the data type.<\/p>\n

    7. Variable Naming Rules<\/h2>\n

    \u2714 Start with a letter or _<\/code>
    \u2714 Can use letters, numbers, _<\/code>
    \u274c Cannot start with number
    \u274c Cannot use keywords<\/p>\n

    Correct Names<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    student_name = \"Anil\"<\/span>
    \n_age = 20<\/span>
    \nmarks1 = 450<\/span>
    \n<\/code><\/div>\n<\/div>\n

    Wrong Names<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    1name = \"Error\"<\/span>
    \nclass<\/span> = 10<\/span>
    \ntotal-marks = 80<\/span>
    \n<\/code><\/div>\n<\/div>\n

    8. Multiple Statements in One Line<\/h2>\n

    You can<\/em> write multiple statements, but it\u2019s not recommended.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    x = 5<\/span>; y = 10<\/span>; print<\/span>(x + y)
    \n<\/code><\/div>\n<\/div>\n

    \ud83d\udc49 Better to write in separate lines.<\/p>\n

    9. Python Line Continuation<\/h2>\n

    Long lines can be broken using \\<\/code>.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    total = 10<\/span> + 20<\/span> + \\
    \n30<\/span> + 40<\/span>
    \nprint<\/span>(total)
    \n<\/code><\/div>\n<\/div>\n

    10. Python Code Blocks<\/h2>\n

    A code block<\/strong> is a group of lines with the same indentation.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    if<\/span> 5<\/span> > 2<\/span>:
    \nprint<\/span>(\"Yes\"<\/span>)
    \nprint<\/span>(\"Five is bigger\"<\/span>)
    \n<\/code><\/div>\n<\/div>\n

    Both print lines are inside the if<\/code> block.<\/p>\n

    11. Common Syntax Errors (Beginner)<\/h2>\n

    \u274c Missing indentation
    \u274c Wrong spelling (pritn<\/code>)
    \u274c Missing quotes
    \u274c Using keyword as variable<\/p>\n

    Example Error<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    print<\/span>(Hello)
    \n<\/code><\/div>\n<\/div>\n

    Correct:<\/p>\n

    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    print<\/span>(\"Hello\"<\/span>)
    \n<\/code><\/div>\n<\/div>\n

    12. Simple Practice Examples<\/h2>\n

    Example 1: Print Message<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    print<\/span>(\"Learning Python is easy\"<\/span>)
    \n<\/code><\/div>\n<\/div>\n

    Example 2: Check a Number<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    \n

    number = 10<\/span><\/code><\/p>\n

    if<\/span> number > 5<\/span>:
    \nprint<\/span>(“Number is greater than 5”<\/span>)<\/p>\n<\/div>\n<\/div>\n

    Example 3: User Input<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    name = input<\/span>(\"Enter your name: \"<\/span>)
    \nprint<\/span>(\"Welcome\"<\/span>, name)
    \n<\/code><\/div>\n<\/div>\n

    13. Summary (Python Syntax)<\/h2>\n

    \u2714 Python uses spaces, not { }<\/code>
    \u2714 Indentation is very important
    \u2714 Python is case-sensitive
    \u2714 Comments help humans
    \u2714 Code should be clean and readable<\/p>\n
