How to Print Even Numbers In Python?

In Python, you can print even numbers by using loops and conditional statements. Here's an example code that prints even numbers from 1 to a given limit:

1
2
3
4
5
6
7
8
9

# Define the limit
limit = 20

# Iterate through numbers from 1 to limit
for num in range(1, limit+1):
    # Check if the number is even
    if num % 2 == 0:
        # Print the even number
        print(num)

In this code, we use a for loop to iterate through the range of numbers from 1 to the given limit. Inside the loop, we use an if statement to check if the current number is even by checking its remainder when divided by 2. If the remainder is 0, i.e., the number is divisible by 2, it is an even number and gets printed.

How to write an if condition with multiple checks in Python?

To write an if condition with multiple checks in Python, you can use the logical operators (and, or) to combine multiple conditions. Here's an example:

1
2
3
4
5
6
7
8
9

# Example if condition with multiple checks
value = 10

if value > 5 and value < 15:
    print("Value is between 5 and 15")
elif value >= 15 or value < 5:
    print("Value is either greater than or equal to 15, or less than 5")
else:
    print("Value is not within the specified ranges")

In this example, the if condition checks if the value is greater than 5 and less than 15. If it is, it will print "Value is between 5 and 15". The elif condition checks if the value is either greater than or equal to 15, or less than 5. If any of these conditions are true, it will print "Value is either greater than or equal to 15, or less than 5". If none of the conditions are met, the else block will execute and print "Value is not within the specified ranges".

How to use the print function in Python?

To use the print function in Python, follow these steps:

1. Open your Python editor or IDE (Integrated Development Environment) where you will write your Python code.
2. Create a new Python file or open an existing one.
3. Enter the print function by typing print( in your code. Example: print(
4. Add the content you want to print within the parentheses. Example: print("Hello, World!") or print(42) or print(variable) The content can be a string enclosed in quotes, a number, or a variable holding a value.
5. Close the parentheses. Example: print("Hello, World!") or print(42) or print(variable)
6. Save the file with a .py extension.
7. Run your code by either pressing the run button in your IDE or executing it through the command line. Alternatively, if you are using an interactive Python interpreter or Jupyter notebook, you can directly enter the print statement and get the output.

Once your code is executed, the content within the print function will be displayed in the output. The print function is used to display the specified content on the console or output window.

What is the modulus operator in Python?

The modulus operator in Python is represented by the percent sign (%). It is used to find the remainder of a division between two numbers. For example, if we divide 10 by 3, the quotient is 3 and the remainder is 1. Using the modulus operator in Python, we can calculate the remainder as 10 % 3, which evaluates to 1 in this case.

What is the format function in Python?

The format function in Python is used to format and display variables inside a string. It allows you to add values of variables into a string in a specific format, such as specifying the number of decimal places for a float or the width of a string.

The basic syntax of the format function is:

1

formatted_string = "Some text with {} and {}".format(value1, value2)

In this example, {} serves as a placeholder for the values that will be inserted using the format function. The format method is then called on the string, followed by the values that will be inserted into the placeholders.

There are various formatting options that can be used within the curly braces. For example:

• To specify the number of decimal places for a float: {:.2f} (with 2 decimal places)
• To specify the minimum width of a string: {:<10} (left-aligned with a width of 10)
• To specify the precision of a float: {:.4e} (in scientific notation with 4 decimal places)

The format function in Python is a powerful tool for creating well-formatted strings with dynamic values.
