In Python 2 it would look like this,same rule UTF-8 in and out.īut has to use a library io or codecs and # -*- coding: utf-8 -*- because Python 2 has ASCII default encoding. Print(line)There is no need for # -*- coding: utf-8 -*- in Python 3,because UTF-8 is default. If re.match(r"h.g.", line) and len(line)=7:
With open('ss.txt', encoding='utf-8') as f:
It returns 0 if the string is found and -1 if the string is not found. The find method is passed the required string. Take a empty list to store all the words. This value must be replaced with the file path from your own system in the example below. For example, let’s check where (if any) the word test is in a file called example.txt. If it does, print the line number and end the loop.

The find () method will return -1 if the given text is not present in a file Print line and line number If you need line and line numbers, use the readlines () method instead of read () method. Python How to Find a Word in a File Artturi Jalli To find a word in a file using Python: Specify a target word.
When not specified, just theMake a single variable to store the path of the file. Use the find () method of a str class to check the given string or word present in the result returned by the read () method. There are two ways of adding keywords to the dictionary: in bulk or one-by-one.

So if borrow code from heiner55 it look like this: Use find Method to Search a String in a File in Python A simple find method can be used with the read () method to find the string in the file. Below is the implementation: from collections import Counter. Python Program to find the square root of a number by Newton’s Method asked in RGPV/UTMP B.Tech (CSE-V Sem) Python Lab by Ankit Yadav Goeduhub's Expert ( 5. Inside Python 3 is all strings sequences of Unicode character,if not encode in or Python 3 do not not recognize encoding it will be bytes (b'hello'). So the simple rule is to keep it UTF-8 in and out when reading a file.
In Python 3 open() has build in encoding parameter. Print each files from the listed directory def searchText(path): os.chdir(path) files = os.(Nov-07-2017, 06:37 PM)Micael Wrote: It's in Swedish so there is of course åäö in the file and that's a problem as well.A lot have change regard Unicode,it was one the biggest changes moving to Python 3(as mention bye heiner55 you should use Python 3). For this, we will use FileInput() method to iterate over the data of the file and replace the text. def searchText(path): os.chdir(path) files = os.listdir() print(files) pass searchText(path) Let see how we can search and replace text using the fileinput module. If a file is removed from or added to the directory during the call of this function, whether a name for that file be included is unspecified. Whatever word user will iput here that word will be searched in a file. seachwordcount input ('Enter the word') in this code, user input is collected and stored in a variable. The list is in arbitrary order, and does not include the special entries ‘.’ and ‘.’ even if they are present in the directory. convert the data in lower case and count the occurrence of specific word. Return a list containing the names of the entries in the directory given by path. Os.chdir(path) - Change the current working directory to specified path. To find a word in a file using Python: Specify a target word. After that list the directory and print the files. Output: ‘G:/data/input’ Create a function and list the directoryĬreate a function and change the directory in which you want to search text.
