Here, the file ‘sample.txt’ is taken as input. Python program outputįor the execution of the above program, we need a file as input. The Python program is given below- def sorting(filename):įinally, we store the sorted contents in a file ‘result.txt’. Finally, we store the sorted contents in another file ‘result.txt’. Then we fetch the contents of the file and sort the words in ascending order. ‘sample.txt’ and open it in the ‘read’ mode. Firstly, we call the function ‘sorting’ and pass the name of the file i.e. Now, we will see a Python program to sort the contents of a file. Python program for sorting contents of a file The statement to sort the contents using ‘sort()’ function is-įinally, the Python list ‘words’ contains the sorted contents. Now, we will use an in-built function ‘sort()’ to sort the contents in ascending order. So, we have stored all the words in the Python list ‘words’. Go to step 2 and repeat the steps until the end-of-file (EOF) is reached.Finally, append each word in the temporary list to Python list ‘words’.Split on the line using function ‘split()’ and store it in a temporary Python list.So, we will follow the below steps to fetch the contents. For sorting, firstly we have to fetch the contents of the file. Method for sorting contents of a text file in PythonĪfter opening the file in ‘read’ mode, we have to sort the contents of that file. So, we can proceed to perform the sorting operation. Case 2- The file with this name is present.To resolve this issue, we can save the file in the same directory or we can give the complete path of the file in the statement. Case 1- The file with this name is not present in the directory where the program is stored.Two cases arise after the execution of this statement. After this, we will open the specific file using statement given below. But, we can also take the name of the file from the user as an input. Here, we take the file ‘sample.txt’ for simplicity. To sort the contents of a file, firstly we need to open the file in ‘read’ mode. Notepad sort alphabetically how to#Today, we will get to know how to open a file, a method to sort the contents of an opened file and a Python program that will create another file having the same content in sorted order. That is, we will sort the contents similar to the way in which words are listed in a dictionary. Here, we will sort the contents of a file in ascending order i.e. In the second S/R the part ^.In this tutorial, we will learn a method for sorting the contents of a text file using a Python program. I preferred to use the tabulation character, instead of some spaces, because, with the tabulation character, the complete filenames look all aligned :-) In replacement, the regex \1\t\t$0 rewrites the group 1 ( The extension part ), then two tabulation characters and, finally, the searched string, that is to say the name of each file, with its extension ( part $0 ) The remainder of the search regex (. ) catches the remainder of the standard characters of the current line ( The extension part ) which is stored as group 1, due to the couple of parentheses matches, from the beginning of the current line ^, a maximum, NON empty, of characters, till a literal dot character ( which must be escaped by an antislash character \ in order to be considered as literal ) So, if the filename would be, for instance, “”, this range would be the string will match only a single standard character and not an EOL character The two search regex begin with the modifier (?-s) ( No PCRE_DOTALL ) that ensures that the regex engine will consider the dot special character. Well, I’m back home and here are some explanations on the two S/R : I’ve got to be out for a while ! But, when I’m home, I’ll add some explanations to my regexes, just in case that you’re not acquainted with regular expressions ! Yeah ! Here is our final text, sorted as expected :-)) apple.c
