If you are a Python programmer, you might have run into the NameError name 'chunk' is not defined mistake at some time in your coding trip. This mistake takes place when you attempt to utilize the glob component in your code, yet Python can not locate it.
In this tutorial, we will certainly cover usual sources of the mistake as well as offer options to aid you obtain your code up as well as running promptly. So, allow’s begin!
Why does the NameError: name 'chunk' is not defined mistake happen?
This mistake takes place when you attempt to utilize the glob collection in your Python code, yet Python can not locate the glob collection in its namespace. The adhering to are a few of the circumstances in which this mistake typically takes place.
- You have not imported the chunk component.
- You have imported the chunk component utilizing a various name.
Exactly how to deal with the NameError: name 'chunk' is not defined?
The glob component in Python is made use of to fetch files/pathnames matching a defined pattern. It utilizes wildcards such as * as well as ? to match filenames.
Considering that this component becomes part of the Python Criterion Collection, you do not require to individually mount it. You can just import it as well as begin utilizing it. Allow’s currently check out the above circumstances that might lead to the above mistake thoroughly.
The glob component is not imported
It can occur that you are attempting to utilize the glob component without also importing it. This is due to the fact that Python does not identify the stats collection as well as its features till it is imported right into the code.
For instance, allow’s attempt to utilize the glob component without importing it as well as see what we obtain.
# keep in mind that chunk is not imported
# Obtain all data in the existing directory site with.txt expansion
txt_files = glob.glob(' *. txt').
print( txt_files) Output:
---------------------------------------------------------------------------.
NameError Traceback (newest telephone call last).
Cell In[3], line 4.
1 # keep in mind that chunk is not imported.
2.
3 # Obtain all data in the existing directory site with.txt expansion.
-- > 4 txt_files = glob.glob(' *. txt').
5 print( txt_files).
NameError: name 'chunk' is not definedWe obtain a NameError mentioning that the name glob is not specified. To utilize the glob collection, you require to import it initial.
import chunk.
# Obtain all data in the existing directory site with.txt expansion.
txt_files = glob.glob(' *. txt').
print( txt_files) Output:
['file2.txt', 'file1.txt', 'get_cwd.py.txt', 'learn.txt']
Right Here, we are importing the glob component initially and afterwards utilizing it to obtain the filenames of all the message data (having . txt expansion) in the existing functioning directory site. You can see that we did not obtain any type of mistakes below.
The glob component is imported utilizing a various name
If you import the glob component utilizing a various name, as an example import chunk as gb, and afterwards attempt to utilize the name “chunk” to utilize it, you will certainly obtain a NameError due to the fact that the name “chunk” is not identified in your existing namespace.
Let’s check out an instance.
import chunk as gb.
# Obtain all data in the existing directory site with.txt expansion.
txt_files = glob.glob(' *. txt').
print( txt_files) Output:
---------------------------------------------------------------------------.
NameError Traceback (newest telephone call last).
Cell In[1], line 4.
1 import chunk as gb.
3 # Obtain all data in the existing directory site with.txt expansion.
-- > 4 txt_files = glob.glob(' *. txt').
5 print( txt_files).
NameError: name 'chunk' is not definedWe obtain a NameError: name 'chunk' is not defined. This is due to the fact that we have actually imported the glob component with the name gb yet we’re attempting to utilize it utilizing the name glob.
To repair this mistake, you can either utilize the name that you have actually made use of in the import declaration or import glob without a pen name. Keep in mind that the convention is to utilize import glob (without a pen name) as it is suggested that you follow this convention that it makes your code extra standard as well as makes it very easy to review by various other designers.
Conclusion
In final thought, the “NameError name ‘chunk’ is not specified” mistake can be repaired by importing the chunk component in your Python manuscript. This mistake takes place when the interpreter can not locate the interpretation of the chunk component. By importing the component, you can access its features as well as utilize them in your code. Keep in mind to examine your punctuation as well as phrase structure when importing the component, as mistakes in the import declaration can additionally create this mistake. With these actions, you must have the ability to deal with the “NameError name ‘chunk’ is not specified” mistake as well as proceed with your Python shows.
