我怎么把它打印成小数点后两位？

Question

距离=10

总计=0

范围（1,15）内的天数：

total += distance
print ("Day", days, "travelled",  distance, "miles", "total" , total )
distance *= .8

Answer 1

您可以使用“round”函数

distance = 10
total = 0

for days in range (1,15):
    total += distance
    print ("Day", days, "travelled",  round(distance, 2), "miles", "total" , round(total, 2) )
    distance *= .8
