Related: How to Create and Re-Use Your Own Module in Python Using a Python For Loop With an Array Pay close attention to the single space that's now between the quotes in parenthesis. Like you did for the character count, you can also rewrite the the word count code above by placing the for loop in a variable like this: a = All you need to do in this case is insert a single space between each quotation mark in the parenthesis: a= You can also modify each of the last two code snippets above to create a simple word counter using a for loop. Note: To get the character count, ensure that there is no space between the quotation marks in the parenthesis that follows the count keyword. However, you can also place a for loop in a separate variable and get a similar result by rewriting the code above like this: a= We can also count the number of strings (including spaces) in the variable a using a for loop: a = The code below returns a sequence of each string in a sentence: a = 'How to use a for loop in Python' Let's have a look at how we can use a for loop with strings. The if, ifelse, else, and print statements are all separate lines of code that come together to produce a single suite.Now that you've seen how a for loop works with a list of integers. The following example demonstrates the use of many lines to create a suite. A header line and a suite are required to form a suite for situations such as if, while, def, and class statements. Individual statements in Python are put together to form a single code block.

Python Suites for Multiple Statement Groups In Python, an example of variable definition: Based on the data type, the interpreter also selects where to allocate RAM. You don't have to specify the variable based on the data type in Python because the interpreter does it for you. Python variables are used when you want to store values in a memory region. Python documentation strings (also known as docstrings) are a convenient way for programmers to define Python functions, modules, methods, and classes.Īs illustrated in the example above, you write the definition or documentation string in triple-double quotations. Instead of using three lines to define a,b, and c, you use one line and a semicolon to separate each variable definition ( ). The preceding example demonstrates how you can make your code more compact. In Python, here's an example of declaring many variables in a single line. Semicolons are used to separate numerous statements on a single line ( ).
