It might be the current directory or the path. path_to_file : This is the file’s location.The open() method returns a file object, And the file object has two useful methods for writing text to the file: write() and writelines(). Open: The method helps to open a text file in write( or append) mode. Without with, you need to explicitly call close() method to close the file. The with statement help to close the file automatically without calling the close() method.
Np.savetxt("sample7.With : We have opened file using with statement. Np.savetxt("sample.txt", new_array, delimiter =", ")Īs shown below, we can also use these functions to save multi-dimensional arrays to a text file.

We can save an array to a text file and load it using these two functions, as shown in the code below. In addition to this the NumPy function also offers the numpy.loadtxt() function to load a text file. The function accepts several parameters, including the name of the file, the format, encoding format, delimiters separating the columns, the header, the footer, and comments accompanying the file. We can save an array to a text file using the numpy.savetxt() function. NumPy is a scientific library that offers a range of functions for working with arrays. Similarly, as shown below, we can also write multi-dimensional arrays to a text file using the context manager. Once we opt out of the indentation, the context manager closes the file automatically. Within the scope of the context manager, we have written the array to the text file upon converting it into a string. In the example above, the context manager opens the text file sample.txt, and since the file does not exist, the context manager creates it. The context manager can be implemented using the with keyword shown below. In Python, using the context manager is considered a better practice when managing resources instead of using the open() and close() functions. Unlike the open() function, where we have to close the files once we have opened them using the close() function, the content manager allows us to open and close files precisely when we need them.
Write an Array to Text File Using Content Manager in PythonĪlternatively, we can use the context manager to write an array to a text file. Similarly, we can also create a multi-dimensional array and save it to a text file, as shown below. The text file contents are displayed in the terminal and can also be viewed by physically opening the text file. Using the open() functions, we opened the contents of the text file in reading mode. We have then proceeded to convert the array into string format before writing its contents to the text file using the write function. We have created a text file named sample.txt using the open function in write mode in the example above. Output: Array contents in text_sample.txt: Print("Array contents in sample.txt: ", content) # Displaying the contents of the text file Using these functions, we will create an array using NumPy and write it to a text file using the write function as shown in the program below. Since the open() function is not used in seclusion, combining it with other functions, we can perform even more file operations such as writing and modifying or overwriting files.These functions include the write() and close() functions. Write an Array to Text File Using open() and close() Functions in Python Please note that the open() function will only create a file if it does not exist otherwise, it’s intrinsically used to open files. These methods may be slightly different depending on the format of the file and the operation being performed.īesides the traditional way of creating files by clicking buttons, we can also create files using built-in functions such as the open() function. Python offers a range of methods that can be used for resource handling. Reading and writing files is an important aspect of building programs used by many users.
