简单介绍一点python的佛性。
python开始支持了连不等式,不用再拆开了。
weight = 30
if 18.5 < weight < 25:
print("BMI is considered 'normal'")
if weight > 18.5 and weight < 25:
print("normal")
print(weight)
结果： 30
if 18.5 < weight < 25:
print("BMI is considered 'normal'")
if weight > 18.5 and weight < 25:
print("normal")
print(weight)
结果： BMI is considered ‘normal’ normal 20
python 查看ASCII（美国信息交换标准代码）
print(ord('0'))
print(ord('a'))
print((ord('A')))
3.科学技术法 type()
type(1e-7)
