I have written the following function, it takes in a variable input_name
. The user then inputs some value which is assigned to input_name
. I want to know the best way to make input_name
accessible outside of the function. I know that defining a variable as global, inside a function, means that is can be used outside of the function. However, in this case the variable as actually a parameter of the function so I am not sure how to define it as a global variable. I appreciate any help with this, please find the code in question below:
def input(input_name, prompt):
while True:
data = raw_input(prompt)
if data:
try:
input_name = int(data)
except ValueError:
print 'Invalid input...'
else:
if input_name >= 0 and input_name < 100:
print 'Congratulations'
break
input_name = 'Please try again: '
else:
print 'Goodbye!'
break
month = 0
day = 0
year = 0
century = 0
input(month, "Please enter the month (from 1-12, where March is 1 and February is 12): ")
input(day, "Please enter the day (from 1-31): ")
input(year, "Please enter the year (from 0 - 99, eg. 88 in 1988): ")
input(century, "Please enter the century (from 0 - 99, eg. 19 in 1988): ")
A = month
B = day
C = year
D = century
The simplest thing would be to return the value, and assign it outside the function:
def my_input(prompt):
#.. blah blah..
return the_value
month = my_input("Please enter the month")
# etc.
Other people are saying something like this:
def input(prompt):
return value
value = input(param1,param2, ...)
And that's what you really want to be doing, but just so you know, you can use globals() for changing global variables:
def input(input_name, prompt):
globals()[input_name] = value
What you want to do is probably a bad practice. Just return input_name
from the input
function.
def input(param1,param2):
return value
value = input(param1,param2, ...)
