spyder

sudo apt-get install spyder 报错：ERROR: Could not find a version that satisfies the requirement pyqt5<5.13;... 百度了半天还是没有解决，于是看了一下 sudo apt-cache search spyder 相关的包原来不少，再尝试 sudo apt-get install spyder3 安装成功，再执行sudo apt-get install spyder也安装成功 附：pip安装使用国内源，参见 https://www.cnblogs.com/pangzhi/p/8196144.html 来源： https://www.cnblogs.com/qq812256/p/11335908.html

I have been using Spyder installed with with Anaconda distribution which uses Python 2.7 as default. Currently I need to set up a development virtual environment with Python 3.4. Top two suggestions after research online are: to set up virtual environment first and to point change the preferences of Spyder , e.g here ; to install all Spyder dependencies, like PyQt4, in the virtual environment itself, e. g. here ; Both recommendations are cumbersome and do not look like smart options for development. Is there a solution that would allow to run Spyder with required Python version automatically

I'm trying to use the max function in Python 3,6: print('Maximum is:', max(1, 3, 2, 5, 4)) And the result is File "E:/ProgramyRobione/untitled1.py", line 2, in <module> print('Maximum is:', max(1, 3, 2, 5, 4)) TypeError: 'int' object is not callable I'm using Spyder and that line is all that code should do. This is a bit of an iPython headshot that comes with Spyder. I've fallen foul of this when copy/pasting random bits of code from SO to test only to find really odd behaviour several days later - variables defined in the iPython console will also be in the script's global namespace
