I learned this the hard way: [WayBack] Different result when using -ReadCount with Get-Content: because -ReadCount delivers data in chunks, the filter after [WayBack] Get-Content (Microsoft.PowerShell.Management) it will only filter on those chunks. If the filter isn’t prepared for that, it might only filter the last chunk.
So do not use for instance [WayBack] Select-String (Microsoft.PowerShell.Utility) on it, but perform your own [WayBack] ForEach-Object (Microsoft.PowerShell.Core) aliased as foreach like in [WayBack] Get all lines containing a string in a huge text file – as fast as possible?:
Get-Content myfile.txt -ReadCount 1000 | foreach { $_ -match "my_string" }
A more elaborate example is at [WayBack] How can I make this PowerShell script parse large files faster?.

One of the things when I learned Python was that in some scripts I found a block starting with a statement like this:
if __name__ == '__main__':
It looked like an idiom to me, and indeed it is: [WayBack] What is ‘if name == “main“‘ for?.
It allows a file to be both used as “main” standalone program file and a module. That section of code will not be executed if it is loaded as a module.
Part of the idiom is also to put your code in a separate method so this block is as short as possible.
if __name__ == '__main__':
main()
Via: [WayBack] Why is Python running my module when I import it, and how do I stop it? (thanks user166390 and Jeremy Banks for the answers there)
