課題1-Sum from 1 to 100 †

first algorithm # sum and range function
```
print(sum(range(1,101))) 
```

second algorithm # for loop

sum = 0
for x in  range(101):
    sum = sum + x
print(sum)

third algorithm # while loop

i = 1
sum = 0
while i <= 100:
    sum += i
    i += 1
print(sum)

課題2-Sum from a to b #　enter a & b from the keyboard †

a = int(input("Enter first number: "))
b = int(input("Enter last number: "))

print("Sum from",a,"to",b,"is",sum(range(a,b+1)))

課題3-Build a calculator †

num1 = float(input("Enter first number: "))
op = input("Enter operator: ")
num2 = float(input("Enter second number: "))

if op == "+":
    print(num1+num2)
elif op == "-":
    print(num1 - num2)
elif op == "*":
    print(num1 * num2)
elif op == "/":
    print(num1 / num2)
else:
    print("Invalid operator")
