How can I assign the result (res) of the calulation to the variable "memory" and then check if the user input is "M" and if so, then set
x or y = M??
msg_0 = "Enter an equation"
msg_1 = "Do you even know what numbers are? Stay focused!"
msg_2 = "Yes ... an interesting math operation. You've slept through all classes, haven't you?"
msg_3 = "Yeah... division by zero. Smart move..."
msg_4 = "Do you want to store the result? (y / n):"
msg_5 = "Do you want to continue calculations? (y / n):"
oper = ['+', '-', '*', '/']
memory = 0
def solution():
global x
global y
global operation
while True:
print(msg_0)
calc = input()
lst = calc.split(' ')
operation = lst[1]
x = lst[0]
y = lst[2]
if x == str('M'):
x = memory
elif y == str('M'):
y = memory
try:
x = float(lst[0])
y = float(lst[2])
except ValueError:
print(msg_1)
continue
try:
if operation in oper:
break
else:
print(msg_2)

continue

res = 0
if operation == oper[0]:
res = x + y
return res
elif operation == oper[1]:
res = x - y
return res

res = x * y
return res
elif operation == oper[3] and y != 0:
res = x / y
