Anaconda's download file is relatively large (about 500 MB) because Anaconda comes with the most commonly used data science package in Python.

If Python is already installed on your computer, the installation will not affect you in any way. In fact, the default Python used by scripts and programs is the Python that comes with Anaconda.

Note: If you are on a windows 10 system, note that when installing the Anaconda software, right-click the anaconda software → choose to run as an administrator.
Specific installation steps:

Go to the official download page to download. There are two versions to choose from: Python 3.6 and Python 2.7. After selecting the version, click "64-Bit Graphical Installer" or "32-Bit Graphical Installer" to download according to your operating system.
After the download is complete, double-click the downloaded file to start the installer.

Note:
① If you encounter any problems during the installation process, temporarily close the anti-virus software and open it again after the installation procedure is completed.

② If you select "Install for all users" during installation, uninstall Anaconda and reinstall it, only for "me user".

Select "Next".
Read the terms of the license agreement, then check "I Agree" and proceed to the next step.
Unless you are installing as an administrator for all users, just check "Just Me" and click "Next".
In the "Choose Install Location" interface, select the target path to install Anaconda, and then click "Next".

Note:
① The target path cannot contain spaces and cannot be "unicode" encoding.

② Do not install as an administrator unless you are required to install with administrator rights.

In "Advanced Installation Options", do not check "Add Anaconda to my PATH environment variable." ("Add Anaconda to my environment variable."). Because if checked, it will affect the use of other programs. If you use Anaconda, you can use it by opening Anaconda Navigator or in the "Anaconda Prompt" (similar to "Terminal" in macOS) in the start menu.

Unless you plan to use multiple versions of Anaconda or multiple versions of Python, check "Register Anaconda as my default Python 3.6".

Then click "Install" to start the installation. If you want to view the installation details, you can click "Show Details".

Click "Next".
Entering the "Thanks for installing Anaconda!" interface means that the installation is successful, click "Finish" to complete the installation.

Note: If you don't want to know about "Anaconda Cloud" and "Anaconda Support", you can uncheck "Learn more about Anaconda Cloud" and "Learn more about Anaconda Support".

Verify the installation result. You can select the following results to verify whether the installation is successful:

In fact, the installation process is all the way to next. Is it very simple? Don't check to add it to the environment variable. After the installation is complete, you can see the following on the start interface:

At this time, we can right-click Anaconda Prompt in the start interface Anaconda Prompt to open the terminal or type conda list in the command prompt to view the contents of your installation as shown below:
