Hey guys I cannot figure out how to use a while loop to find the smallest number entered by a user. I know I have to assign a number entered to stop the program then print the smallest number that was entered. This is what I have so far:
while(True):
A = int(input("Enter a Number (Use -1 to Stop): " ))
if(A == -1):
break
Any help would be appreciated, thank you.
Initialize the number before the loop, then update its value if the new number is less. This should do:
# initialize minimum
minimum = int(input("Enter a Number: " ))
while(True):
A = int(input("Enter a Number (Use -1 to Stop): " ))
if(A == -1):
break
if minimum > A:
minimum = A
print(minimum)
You could easily store all the values in a list and then use min, but if you insist not to:
min_val = None
while True:
A = int(input("Enter a Number (Use -1 to Stop): " ))
if A == -1:
break
if not min_val or A < min_val:
min_val = A
The if checks whether it is the first value the user inputs or if the new value is smaller than the previous minimum.
When the while breaks, min_val will either be None (if the first value the user inputs is -1) or the minimum value the user entered.
Code below would suit your need:
b = -1
while(True):
A = int(input("Enter a Number (Use -1 to Stop): " ))
if(A == -1):
print b
break
b = b if A > b else A
Good Luck !
