I\'m a big fan of PyCharm by JetBrains but I do run into some issues that I thought maybe I\'ll ask here about.
Regarding the freezing issue, we found this occurred when processing CSV files with at least one extremely long line.
To reproduce:
[print(x) for x in (['A' * 54790] + (['a' * 1421] * 10))]
However, it appears to have been fixed in PyCharm 4.5.4, so if you experience this, try updating your PyCharm.
