How do i strip unicode in python?

IntroductionIn python, we have discussed many concepts and conversions. But sometimes, we come to a situation where we need to remove the Unicode characters from the string. In this tutorial, we will be discussing how to remove all the Unicode characters from the string in python. What are Unicode characters?Unicode is an international encoding standard that is widely spread and has its acceptance all over the world. It is used with different languages and scripts by which each letter, digit, or symbol is assigned with a unique numeric value that applies across different platforms and programs. Here, we will be discussing all the different ways through which we can remove all the Unicode characters from the string: 1. Using encode() and decode() methodIn this example, we will be using the encode() function and the decode() function from removing the Unicode characters from the String. Encode() function will encode the string into ‘ASCII’ and error as ‘ignore’ to remove Unicode characters. Decode() function will then decode the string back in its form. Let us look at the example for understanding the concept in detail. #input string str = "This is Python \u500cPool" #encode() method strencode = str.encode("ascii", "ignore") #decode() method strdecode = strencode.decode() #output print("Output after removing Unicode characters : ",strdecode) Output: Explanation:
2. Using replace() method to remove Unicode charactersIn this example, we will be using replace() method for removing the Unicode characters from the string. Suppose you need to remove the particular Unicode character from the string, so you use the string.replace() method, which will remove the particular character from the string. Let us look at the example for understanding the concept in detail. #input string str = "This is Python \u300cPool" #replace() method strreplaced = str.replace('\u300c', '') #output print("Output after removing Unicode characters : ",strreplaced) Output: Explanation:
3. Using character.isalnum() method to remove special characters in PythonIn this example, we will be using the character.isalnum() method to remove the special characters from the string. Suppose we encounter a string in which we have the presence of slash or whitespaces or question marks. So, all these special characters can be removed with the help of the given method. Let us look at the example for understanding the concept in detail. #input string str = "This is /i !? Python pool tutorial?"" output = "" for character in str: if character.isalnum(): output += character print(output) Output: Explanation:
4. Using regular expression to remove specific Unicode characters in PythonIn this example, we will be using the regular expression (re.sub() method) for removing the specific Unicode character from the string. This method contains three parameters in it, i.e., pattern, replace, and string. Let us look at the example for understanding the concept in detail. #import re module import re #input string str = "Pyéthonò Poòol!" #re.sub() method Output = re.sub(r"(\xe9|\362)", "", str) #output print("Removing specific charcater : ",Output) Output: Explanation:
5. Using ord() method and for loop to remove Unicode characters in PythonIn this example, we will be using the ord() method and a for loop for removing the Unicode characters from the string. Ord() method accepts the string of length 1 as an argument and is used to return the Unicode code point representation of the passed argument. Let us look at the example for understanding the concept in detail. #input string str = "This is Python \u500cPool" #ord() function output = ''.join([i if ord(i) < 128 else ' ' for i in str]) #output print("After removing Unicode character : ",output) Output: Eplanation:
ConclusionIn this tutorial, we have learned about the concept of removing the Unicode characters from the string. We have discussed all the ways through which we can remove the Unicode characters from the string. All the ways are explained in detail with the help of examples. You can use any of the functions according to your choice and your requirement in the program. However, if you have any doubts or questions, do let me know in the comment section below. I will try to help you as soon as possible. How do I strip Unicode?5 Solid Ways to Remove Unicode Characters in Python. Using encode() and decode() method..
