b = 3
c = a / b
d = a % b
print(c)
print(int(c))
print(d)


# 2. 賦值運算子
# =  +=  -=
e = 5
print(e)
e += 5
print(e)
e -= 5
print(e)

# 3. 比較運算子
#  ==  >  <  >=  <=  !=
# 比較運算結果為布林值:True  False

i = 10
j = 5
print(i > j)
print(i < j)

# 4. 邏輯運算子
# and or not  與或非
# and: 真真為真
# or : 假假為假
m = 5
n = -6
print(m > 0 and n > 0)
print(m > 0 or n < 0)

# in0
# not in
s = 'elf'
print('e' in s)
print('e' not in s)
