title: Biggest python projects
body: <p>What is the biggest software development team that uses Python? I am wondering how well the dynamic type system scales to large development teams.</p>
  
  <p>It's pretty clear that at Google they have C++ and Java codebases with thousands of developers; their use of Python is much smaller.</p>
  
  <p>Are there some huge companies that develop primarily in Python?</p>
