What's wrong with raw_input() (EOFError: EOF when reading a line)

I am using python 2.7.6, and when calling raw_input(), there is an exception:

flight_name = raw_input('\nEnter the name of Flight: ')

I found the solution, but why there appears such exception? Is it a bag?

try:
      flight_name = raw_input('\nEnter the name of Flight: ')
except (EOFError):
      break

I'm using PyCharm.

This answer 

sys.stdin = open('/dev/tty')
answer = raw_input('Commit anyway? [N/y] ')

is useful if you've previously read from sys.stdin in your code. In that case, the raw_input line will throw the EOF error without waiting for user input, if you set the sys.stdin = open('/dev/tty') just before raw_input, it resets the stdin and allows the user input to work. (tested in python 2.7) with 

## test.py
import sys
for line in sys.stdin:
  pass
#sys.stdin = open('/dev/tty')
raw_input("Are you sure?")

echo 'abc' | python test.py

Which raises:

EOFError: EOF when reading a line

Until you uncomment the 2nd to last line.

You could use:

sys.stdin = open('/dev/tty')
answer = raw_input('Commit anyway? [N/y] ')

You're trying to read something from standard input but you're not getting anything, only the EOF. This actually lets you know the user is not providing any input and you can do other things for this condition.
