Python syntax is simple and easy to read, making it one of the most beginner-friendly programming languages. It follows a clean structure that resembles natural language, allowing developers to write concise and readable code. Below is an overview of Python’s basic syntax.

## **1. Writing and Executing Python Code**

Python code can be written in an interactive shell or saved as a script file (.py) and executed. The Python interpreter reads and executes the code line by line.

Example:



```txt
print("Hello, Python!")
```

**Output:**



```txt
Hello, Python!
```

Python files are typically saved with the .py extension and executed using:

python filename.py

## **2. Case Sensitivity**

Python is case-sensitive, meaning that variable, Variable, and VARIABLE are treated as different identifiers.

Example:



```txt
name = "Alice"
Name = "Bob"

print(name)  # Alice
print(Name)  # Bob
```

## **3. Statements and Expressions**

* A **statement** is a complete instruction in Python.
* An **expression** is a combination of values and operators that evaluate to a single value.

Example:

```txt
x = 5  # Statement
y = x + 10  # Expression
print(y)  # 15
```

## **4. Comments in Python**

Comments are used to annotate code and are ignored by the Python interpreter.

**Single-line comment:** Uses #


```txt
# This is a comment
print("Hello, World!")  # This prints a message
```

**Multi-line comment:** Uses triple quotes (''' or """)



```txt
"""
This is a multi-line comment.
It spans multiple lines.
"""
print("Python is easy to learn!")
```

**5. Line Breaks and Continuation**

Python automatically detects the end of a statement when a new line starts. However, if a statement is too long, you can use \ for line continuation.

Example:



```txt
total = 5 + 10 + 15 + \
        20 + 25
print(total)  # 75
```

For better readability, you can also enclose expressions in parentheses:



```txt
total = (5 + 10 + 15 +
         20 + 25)
print(total)  # 75
```

## **6. Quotes in Strings**

Python supports single ('), double ("), and triple (''' or """) quotes for string literals.

Example:



```txt
print('Hello')  
print("Hello")  
print('''Hello''')  
print("""Hello""")  
```

## **7. Escape Characters**

Escape characters are used to include special characters in a string.

Example:



```txt
print("This is a new line\nThis is another line")  # \n for newline
print("He said, \"Python is great!\"")  # \" to include quotes
```

**Output:**



```txt
This is a new line
This is another line
He said, "Python is great!"
```

## **8. Importing Modules**

Python allows importing built-in or custom modules using the import keyword.

Example:



```txt
import math
print(math.sqrt(25))  # 5.0
```

To import specific functions:



```txt
from math import sqrt
print(sqrt(25))  # 5.0
```
