Why does Importerror: Cannot Import NameError Occurs?
Below, are the reason that’s why Importerror: Cannot Import Name occurs in Python:
- Circular Import
- Incorrect Module Reference
- Typo in Import Statement
Circular Import
Below, the code consists of two Python modules, `module_a.py` and `module_b.py`. `module_a` imports `function_b` from `module_b`, and `module_b` imports `function_a` from `module_a`, creating a circular dependency. This circular import structure can lead to the “ImportError: Cannot Import Name” when attempting to use functions from either module.
module_a.py
Python3
# module_a.py from module_b import function_b def function_a(): print ( "Function A" ) |
module_b.py
Python3
# module_b.py from module_a import function_a def function_b(): print ( "Function B" ) |
Output:
Hangup (SIGHUP)
Traceback (most recent call last):
File "Solution.py", line 2, in <module>
from module_b import function_b
Importerror: No module named 'module_b'
Incorrect Module Reference
In below, code `main.py` attempts to import `my_function` from `mymodule`, but `mymodule.py` defines a function named `another_function`. This inconsistency causes an `ImportError: Cannot Import Name` when calling `my_function()` in `main.py`.
main.py
Python3
# main.py from mymodule import my_function my_function() |
mymodule.py
Python3
# mymodule.py def another_function(): print ( "Another Function" ) |
Output:
Hangup (SIGHUP)
Traceback (most recent call last):
File "Solution.py", line 2, in <module>
from mymodule import my_function
Importerror: No module named 'mymodule'
Typo in Import Statement
In `myscript.py`, an attempt to import and execute `my_function` from `utils` causes an `ImportError: Cannot Import Name` because the function is defined later in `utils.py`. To resolve, switch the order of the import statement and function definition in `utils.py`.
myscript.py
Python3
# myscript.py from utils import my_function my_function() |
utils.py
Python3
# utils.py def my_function(): print ( "My Function" ) |
Output:
Hangup (SIGHUP)
Traceback (most recent call last):
File "Solution.py", line 2, in <module>
from utils import my_function
Importerror: No module named 'utils'
Importerror: Cannot Import Name In Python
One common error that developers encounter is the “ImportError: Cannot Import Name.” This error occurs when the Python interpreter is unable to import a particular name or module within your code. In this article, we’ll explore what causes this error and provide solutions to fix it.
What is ImportError: Cannot Import Name?
The “ImportError: Cannot Import Name” error typically occurs when there is a circular import or a dependency loop in your Python code. Circular imports happen when two or more modules depend on each other, creating a loop that confuses the interpreter. As a result, Python raises an ImportError because it cannot determine the correct order of module imports.
Syntax:
Importerror: Cannot Import Name
