Python method to get the current path:
import os,sys
Use sys.path[0], sys.argv[0], os.getcwd(), os.path.abspath(__file__), os.path.realpath(__file__)
sys.path is a list of search paths that Python will use to find modules, sys.path[0] and sys.argv[0] is the same thing because Python will automatically add sys.argv[0] to sys.path.
If you execute python getpath\getpath.py in the C:\test directory, then os.getcwd() will output "C:\test" and sys.path[0] will output "C:\ test\getpath".
If you use the py2exe module to compile a Python script into an executable file, the output of sys.path[0] will also change:
If the dependent library is packaged as a zip file in the default way, then sys.path[0] will output "C:\test\getpath\libarary.zip";
If the zipfile=None parameter is specified in setup.py, the dependent library will be packaged into the exe file, then sys. path[0] will output "C:\test\getpath\getpath.exe".
#!/bin/env python #-*- encoding=utf8 -*- import os,sys if __name__=="__main__": print "__file__=%s" % __file__ print "os.path.realpath(__file__)=%s" % os.path.realpath(__file__) print "os.path.dirname(os.path.realpath(__file__))=%s" % os.path.dirname(os.path.realpath(__file__)) print "os.path.split(os.path.realpath(__file__))=%s" % os.path.split(os.path.realpath(__file__))[0] print "os.path.abspath(__file__)=%s" % os.path.abspath(__file__) print "os.getcwd()=%s" % os.getcwd() print "sys.path[0]=%s" % sys.path[0] print "sys.argv[0]=%s" % sys.argv[0] 输出结果: D:\>python ./python_test/test_path.py __file__=./python_test/test_path.py os.path.realpath(__file__)=D:\python_test\test_path.py os.path.dirname(os.path.realpath(__file__))=D:\python_test os.path.split(os.path.realpath(__file__))=D:\python_test os.path.abspath(__file__)=D:\python_test\test_path.py os.getcwd()=D:\ sys.path[0]=D:\python_test sys.argv[0]=./python_test/test_path.py
os.getcwd() "D:\", the starting execution directory is taken
sys.path[0] or sys.argv[0] "D:\python_test", taken It is the directory where the initially executed script is located
os.path.split(os.path.realpath(__file__))[0] "D:\python_test", which takes the location of the file test_path.py where __file__ is located Directory
Correctly obtain the current path:
__file__是当前执行的文件 # 获取当前文件__file__的路径 print "os.path.realpath(__file__)=%s" % os.path.realpath(__file__) # 获取当前文件__file__的所在目录 print "os.path.dirname(os.path.realpath(__file__))=%s" % os.path.dirname(os.path.realpath(__file__)) # 获取当前文件__file__的所在目录 print "os.path.split(os.path.realpath(__file__))=%s" % os.path.split(os.path.realpath(__file__))[0]

This tutorial demonstrates how to use Python to process the statistical concept of Zipf's law and demonstrates the efficiency of Python's reading and sorting large text files when processing the law. You may be wondering what the term Zipf distribution means. To understand this term, we first need to define Zipf's law. Don't worry, I'll try to simplify the instructions. Zipf's Law Zipf's law simply means: in a large natural language corpus, the most frequently occurring words appear about twice as frequently as the second frequent words, three times as the third frequent words, four times as the fourth frequent words, and so on. Let's look at an example. If you look at the Brown corpus in American English, you will notice that the most frequent word is "th

PDF files are popular for their cross-platform compatibility, with content and layout consistent across operating systems, reading devices and software. However, unlike Python processing plain text files, PDF files are binary files with more complex structures and contain elements such as fonts, colors, and images. Fortunately, it is not difficult to process PDF files with Python's external modules. This article will use the PyPDF2 module to demonstrate how to open a PDF file, print a page, and extract text. For the creation and editing of PDF files, please refer to another tutorial from me. Preparation The core lies in using external module PyPDF2. First, install it using pip: pip is P

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
