python3.4 can be used directly from the BS4 import BeautifulSoup

Note: Installing 2.7 and 3.4 on the same computer will cause the PIP command to not install in 2.7 cases BEAUTIFULSOUP4

==================================

Python script is ok, but execution total error "Attributeerror: ' Module ' object has no attribute ' xxx '". There is a problem with the. pyc file.
Problem Locator:
View the source file of the import library, discover that the source file exists without errors, and that the. pyc file exists for the source file.
Problem Solving methods:
1. When naming the Py script, do not match the python reserved word, module name, etc.
2. Delete the. pyc file for the library (because the. pyc file is generated by the PY script each time it is run; if the. pyc file is already generated, the runtime will still walk PYC if the code is not updated, so delete the. pyc file) and rerun the code;
Or find an environment where you can run the code, and copy the. pyc file that replaces the current machine.

-------------------------

PYc File Description
The PYc file, which is a python-compiled bytecode (bytecode) file. As soon as you run the py file, the Python compiler will automatically generate a corresponding PYC bytecode file. This PYC bytecode file, after the Python interpreter, generates machine code to run (which is why the PYc file can be deployed across platforms, similar to Java's cross-platform, a bytecode file run by the JVM in Java). The next call calls PYc directly, without invoking the py file. Until you have changed this py file. The Python interpreter checks the build time in the PYc file to compare the modification time of the Py file and, if the PY is updated, generates a new PYC.
