You might have used various functions in Python. While working with functions, there may be an error called “TypeError expected string or bytes-like object”. This is usually encountered when a function that you are using or have defined is fed an integer or float. It might be expecting a string or byte like object but as it has received something else, it raises an error.
The way to fix this error is to pass the correct argument to the function. You can change the syntax or convert the parameters into the required types.
We will take a closer look at the different scenarios where the error is raised. Subsequently, we will try to find their solutions.
Examples of TypeError expected string or bytes-like object
import re # Declared Variable as Integer strtoreplace = 1121 textonly = re.sub("[^a-zA-Z]", " ",strtoreplace) print('Print Value: ', textonly)
Traceback (most recent call last): File "pyprogram.py", line 6, in <module> textonly = re.sub("[^a-zA-Z]", " ",strtoreplace) File "C:\Python38\lib\re.py", line 208, in sub return _compile(pattern, flags).sub(repl, string, count) TypeError: expected string or bytes-like object
import re # Declared Variable as Integer strtoreplace = 1121 textonly = re.sub("[^a-zA-Z]", " ",str(strtoreplace)) print('Print Value: ', textonly)
This error is encountered as there a couple of values in the code that are floats. In order to run the code successfully, you have to convert some value into strings. Before passing the values into the re.sub() function, you can convert into a string using the str() function.
