If we want to get the list of all files and the specified directory’s directory, we have to use os.listdir(). Using os.listdir() in Python to loop through files in a directory What is os.listdir()? 5 Ways in Python to loop through files in a directoryġ. It has a function to interact with an operating system. The module is useful to change the current working directory, iterate over files, get the working directories, etc. This module is useful for working with directories. The os is a module that is already available in python. Frequently Asked Questions Related to Python loop through files in directory.Iterate over files with certain extension using glob module Using glob module in Python to loop through files in a directory Iterate over files with certain extension using os.walk() Using os.walk() in Python to loop through files in a directory Iterate over files with certain extension using pathlib module
Using pathlib module in Python to loop through files in a directory Iterate over files with certain extension using os.scandir() Using os.scandir() in Python to loop through files in a directory Iterate over files with certain extension using os.listdir() Code to get the list of files in a current working directory 1.1 Code to get the list of directories in a specified path.Using os.listdir() in Python to loop through files in a directory 5 Ways in Python to loop through files in a directory.The break statement comes in handy to exit a loop if a specified condition is met.įor example, let’s say we want to exit the loop in the above-mentioned program when the value of the variable “number” reaches “5”. We can combine while loops with other statements to perform certain actions. If we do not increment the value of “number”, the condition will never become false and the loop will run forever. This process is repeated again and again until the value of “number” becomes “11” and the loop is terminated because the condition is now false. Then the next line of code increments the value of “number”. The function “print(number)” prints whatever the value of the “number” variable. As a result, the body of the While loop will get executed. In the first iteration, the “number” will be “1” and the condition “number <= 10” of the While loop will be true. On the second line, we used a loop and gave it a condition i.e. First, we declared a variable named “number” and give it a value “1”. Now let’s discuss how the code given above is actually working. We can use the same code to output any sequence of numbers by just changing the condition. In this simple program, we have concised 10 lines of code into just four lines. Following is the syntax while loop uses in python programing language: We should first discuss the syntax of a while loop in python before going any further. We can think of a while loop as a repeating if statement, to make the concept easier to understand. In most cases loops are interchangeable with each other but while loop should be preferred over other loops when the required condition is boolean. Today we will only learn about while loop and where it should be preferred over other kinds of loops. Many programming languages have several types of loops and the most renowned ones are while and for loop. The syntax for loops in each language may differ but the logic being used remains the same. Most modern programming languages do include the concept of loops. In programming languages, loops are a set of instructions that execute a sequence of code continuously until a certain condition is fulfilled. Unlike HTML or CSS, general-purpose programming languages are used in several application domains. Python is a renowned general-purpose programming language.
