# mymax2.py
# Write max function without built-in max().
def mymax2(x, y):
"""Return larger of x and y."""
largest_so_far = x
if y > largest_so_far:
largest_so_far = y
return largest_so_far
def main():
print("MyMax: Enter two values to find the larger.")
first = float(input("First value: "))
second = float(input("Second value: "))
print("The larger value is", mymax2(first, second))
main()
执行：
#!python
$ python3 mymax2.py
MyMax: Enter two values to find the larger.
First value: 3
Second value: 89
The larger value is 89.0
注意赋值是=，判断是否等于是==。
python的基础数据类型有bool、float、int、str
