Idle editor crashes when input size more than 250 lines given.
Steps to reproduce:-
try with below snippet of code
for i in range(250):
 n=input()
Execute the snippet of code. But while giving the input copy all 250 inputs with single paste.
Editor is crashed. On clicking it's giving "Not responding"
System Config:-
OS - Windows 10
Python Version - 3.5.2

Please describe more exactly the pasting. Also try the same when you run the same code in the standard python interpreter. Same or different behavior? Also, what system? Pasting varies a bit between OSes. Is '250' needed'?

Attaching the exact snippet of code that caused idle crash.issue.py file contains the code and input.txt contains input used.
Also tried with python interpreter. In python interpreter issue is not seen. It's displaying the output.
Pasting of input was done by copying the contents from the notepad file to idle. 
Output is 2 dimensional array in the script(variable 'a'). I think due to the size of the output idle is crashing. But issue is not seen in python interpreter. 
System Config:-
Operating system - Windows 10 64 Bit
Python Version - 3.5.2
IDLE version - 3.5.2
Tk version - 8.6.4

200 (lines) * 200 (columns) * 3 (or more chars/item) = line with 120000+ chars -- which you try to print 200 times. This is known to mostly freeze tk Text windows. This was not a crash for me, as I was able to close Shell and continue.
PS: Please post uncompressed files next time.
