My python program has two calls to raw_input()
The first raw_input()
is to take multiline input from the user. The user can issue Ctrl+D (Ctrl+Z in windows) for the end of input.
Second raw_input()
should take another input from user with (y/n) type prompt.
Unfortunately (in Mac OS X only?), second raw_input()
raises EOFError
when the stdin is terminated (with Ctrl+D) at first raw_input()
prompt.
Please see my example code below for more explanation -
mailBody = ''
signature = 'Later!'
print 'Compose your mail:'
while True:
try:
# Hit ^D after entering some text
mailBody+= raw_input()
mailBody+='\n'
except EOFError:
break
# This raw_input() throws EOFError too. Because, stdin is terminated for the session
# when EOF (^D) is issues at first raw_input() method (Where as, it doesn't raise EOFError in Linux)
opt = raw_input("Do you want to add signature to your mail? (y/N): ").lower()
print '-'*10+'Your Mail'
if opt == 'y':
print mailBody+"\n"+signature
else:
print mailBody
print '-'*19
The program output:
-1- abhinay@MacBook code/py % python prompt.py
Compose your mail:
hello there!
how is everybody?
Do you want to add signature to your mail? (y/N): Traceback (most recent call last):
File "prompt.py", line 11, in <module>
opt = raw_input("Do you want to add signature to your mail? (y/N): ").lower()
EOFError
How can I make second prompt not to raise EOFError
. Please help!
EDIT:
I've edited my question to keep it simple.
I ran my above code in Linux System, it works without any issue. That is, the user was prompted at second raw_input() to receive '(y/N)' choice.
