1.Problem with input() in Spyder 5.1.5 (Anaconda)

Reasons for incompatible Spyder versions and solutions:
1 Upgrade to (5.3.0)
2 If anaconda is not compatible with the latest version, you can only upgrade to 5.1.5, create a new environment conda-forge packages, and enter the following codes in Anaconda Prompt:

 conda create -n spyder-cf -c conda-forge spyder
 conda activate spyder-cf
 pip install spyder==5.3.0
