Get the current pandas version number
pandas is a popular Python data analysis library that is widely used in data processing and data analysis. When using pandas for data analysis, it is necessary to know the pandas version number currently used. This article will introduce in detail how to obtain the current pandas version number and provide specific code examples.
There are two main ways to obtain the current pandas version number: through the properties of the pandas library and through the pip package management tool.
Method 1: Through the attributes of the pandas library
The pandas library itself provides an attribute __version__, which can be directly accessed to obtain the current pandas version number. The following is a code example to obtain the current pandas version number:
import pandas as pd
pandas_version = pd.__version__
print("当前pandas版本号为：", pandas_version) In the above code, we access the __version__ attribute of the pandas library through pd.__version__ and assign the result Give the variable pandas_version, and then use the print function to output the current pandas version number.
Method 2: Through the pip package management tool
If you use the pip package management tool to install and manage the Python library, you can view and obtain the current pandas through the show command of pip version number. The following is a code example for obtaining the current pandas version number through the pip package management tool:
import subprocess
result = subprocess.check_output(['pip', 'show', 'pandas']).decode('utf-8')
version_line = [line for line in result.split('
') if line.startswith('Version')][0]
pandas_version = version_line.split(':')[1].strip()
print("当前pandas版本号为：", pandas_version) In the above code, we use the subprocess.check_output function to execute pip show pandas command and returns the result as a string. Then, we obtain the line containing the version number through string processing and extract the version number.
Whether we use method one or method two, we can easily get the current pandas version number. This is of great significance in many situations. For example, during project deployment, it is necessary to ensure that the version of the running environment matches the version required by the code.
Summary
This article introduces two methods to obtain the current pandas version number: through the properties of the pandas library and through the pip package management tool. By directly accessing the __version__ attribute, you can directly obtain the current pandas version number; by calling pip's show command, you can obtain detailed information about the current pandas version and extract the version number. No matter which method is used, the current pandas version number can be easily obtained so that we can perform version control and troubleshooting during the data analysis process.
