zl=[]
with open("a.txt") as f:
for l in f:
txtline=l.rsplit()
for ll in txtline:
#print(ll)
if ll[0]=="Z":
x=float(ll[1:])
zl.append(x)
#方法一:使用python内建的max min函数
print("大: ",max(zl))
print("小: ",min(zl))
#方法二: 使用sorted排序后取首位和末尾元素。
zl=sorted(zl)
print("小: ",zl[0])
print("大: ",zl[-1])
#总结是不管是max 还是sort 比较的对象都应该统一是数字。
#所以处理前需要先丢掉字母Z并转成浮点数。
