1. What is a String?<\/h2>\n

A string<\/strong> is text<\/strong>.<\/p>\n

In Python, any text written inside:<\/p>\n

    \n
  • \n

    \" \"<\/code> (double quotes) or<\/p>\n<\/li>\n

  • \n

    ' '<\/code> (single quotes)<\/p>\n<\/li>\n<\/ul>\n

    is called a string<\/strong>.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    name = \"Python\"<\/span>
    \ncity = 'Delhi'<\/span>
    \n<\/code><\/div>\n<\/div>\n

    2. Printing a String<\/h2>\n

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

    Print a String Variable<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    language = \"Python\"<\/span>
    \nprint<\/span>(language)
    \n<\/code><\/div>\n<\/div>\n

    3. String Length<\/h2>\n

    You can find how many characters are in a string using len()<\/code>.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    word = \"Python\"<\/span>
    \nprint<\/span>(len<\/span>(word))
    \n<\/code><\/div>\n<\/div>\n

    Output:<\/p>\n

    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    6
    \n<\/code><\/div>\n<\/div>\n

    4. Accessing Characters (Indexing)<\/h2>\n

    Each character in a string has a position (index).<\/p>\n

    Index starts from 0<\/strong>.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    text = \"Python\"<\/span>
    \nprint<\/span>(text[0<\/span>]) # P<\/span>
    \nprint<\/span>(text[1<\/span>]) # y<\/span>
    \nprint<\/span>(text[-1<\/span>]) # n<\/span>
    \n<\/code><\/div>\n<\/div>\n

    5. Slicing Strings<\/h2>\n

    Slicing means taking a part of the string.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    text = \"Programming\"<\/span><\/p>\n

    print<\/span>(text[0<\/span>:4<\/span>]) # Prog<\/span>
    \nprint<\/span>(text[4<\/span>:]) # ramming<\/span>
    \nprint<\/span>(text[:6<\/span>]) # Progra<\/span>
    \n<\/code><\/div>\n<\/div>\n

    6. Joining Strings (Concatenation)<\/h2>\n

    You can join strings using +<\/code>.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    first = \"Hello\"<\/span>
    \nsecond = \"World\"<\/span><\/p>\n

    print<\/span>(first + \" \"<\/span> + second)
    \n<\/code><\/div>\n<\/div>\n

    7. String with Numbers<\/h2>\n

    Strings and numbers cannot be joined directly.<\/p>\n

    \u274c Wrong Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    age = 25<\/span>
    \nprint<\/span>(\"Age is \"<\/span> + age)
    \n<\/code><\/div>\n<\/div>\n

    \u2714 Correct Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    print<\/span>(\"Age is \"<\/span> + str<\/span>(age))
    \n<\/code><\/div>\n<\/div>\n

    OR (easy way)<\/p>\n

    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    print<\/span>(\"Age is\"<\/span>, age)
    \n<\/code><\/div>\n<\/div>\n

    8. Common String Methods<\/h2>\n

    Python has many built-in string functions.<\/p>\n

    Uppercase<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    text = \"python\"<\/span>
    \nprint<\/span>(text.upper())
    \n<\/code><\/div>\n<\/div>\n

    Lowercase<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    print<\/span>(text.lower())
    \n<\/code><\/div>\n<\/div>\n

    Capitalize First Letter<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    print<\/span>(text.capitalize())
    \n<\/code><\/div>\n<\/div>\n

    Replace Text<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    text = \"I like Java\"<\/span>
    \nprint<\/span>(text.replace(\"Java\"<\/span>, \"Python\"<\/span>))
    \n<\/code><\/div>\n<\/div>\n

    9. Checking Text in a String<\/h2>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    text = \"Python is easy\"<\/span><\/p>\n

    print<\/span>(\"Python\"<\/span> in<\/span> text)
    \nprint<\/span>(\"Java\"<\/span> in<\/span> text)
    \n<\/code><\/div>\n<\/div>\n

    10. Taking String Input from User<\/h2>\n

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

    11. Multiline Strings<\/h2>\n

    You can write text in many lines using triple quotes.<\/p>\n

    Example<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    message = \"\"\"Welcome to Python
    \nThis is a simple string example
    \nEnjoy learning\"\"\"<\/span>
    \nprint<\/span>(message)
    \n<\/code><\/div>\n<\/div>\n

    12. Common Beginner Mistakes<\/h2>\n

    \u274c Missing Quotes<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    name = Python
    \n<\/code><\/div>\n<\/div>\n

    \u2714 Correct:<\/p>\n

    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    name = \"Python\"<\/span>
    \n<\/code><\/div>\n<\/div>\n

    \u274c Wrong Index<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    text = \"Hi\"<\/span>
    \nprint<\/span>(text[5<\/span>])
    \n<\/code><\/div>\n<\/div>\n

    \u274c Error: index out of range<\/p>\n

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

    Example 1: Print Full Name<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    first_name = \"Amit\"<\/span>
    \nlast_name = \"Sharma\"<\/span><\/p>\n

    print<\/span>(first_name + \" \"<\/span> + last_name)
    \n<\/code><\/div>\n<\/div>\n

    Example 2: Count Letters<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    word = \"Apple\"<\/span>
    \nprint<\/span>(len<\/span>(word))
    \n<\/code><\/div>\n<\/div>\n

    Example 3: Change Case<\/h3>\n
    \n
    \n
    \n
    <\/div>\n<\/div>\n<\/div>\n
    text = \"python programming\"<\/span>
    \nprint<\/span>(text.upper())
    \n<\/code><\/div>\n<\/div>\n

    14. Summary (Python Strings)<\/h2>\n

    \u2714 Strings are text
    \u2714 Written inside quotes
    \u2714 len()<\/code> gives length
    \u2714 Index starts from 0
    \u2714 Many useful string methods<\/p>\n
