Addition of multiple numbers in python
I wrote a code like this def add(*args): sum = 0 for i in args: sum = sum + i return sum print(add(3,4)) I directly given values in the add function call. How can I get values from the user? And also tell me how to print an error message when user enters any alphabet or special character ??

def add(args):
sum = 0
for i in args:
sum = sum + i
return sum
#try like this
a = []
try:
a = list(map(int, input().split()))
except:
print("Please enter Numeric values only")
exit()
print(add(a))
Try thus code and pass space seperated values in single line
Ex input : 1 2 3 4

Pardha Saradhi My code requires all the inputs to be in separate lines. If you want the numbers to be in a single line, then try this one:
try: print(add(*map(int, input().split())))
except: print("Please enter a valid input!")

Calvin Thomas Thank you. But when I run that code, I given Many numbers as input but did not get the answer. I don't know what to give to get output. Can you please tell me

exit() is used to stop the execution of program at the point where it is used, I have used this so that you can only see the error message that we are providing to user and not the error generated by python.

try:
def s(*x):
s = sum([float(i) for i in x])
return s
n = input().split()
x = list(map(float,n))
print(s(*x))
except:
print("input error")
# you must input digit separated by space. Ex: 1 2 3
#it's outputting real number
#hope this help

Pariket where can I use that input () function

Or if you want multiple inputs you can even use list for that

Pardha Saradhi Here's a possible solution:
def add(*args): return sum(args)
inp = []
try:
while 1: inp.append(int(input()))
except ValueError:
print("Please enter a valid input!")
exit()
except EOFError: print(add(*inp))
# Hope this helps

Run the code and see the output window you will find the error message for user followed by the error message generated by python
Hope this helps 😊
