从输入的数组中减去数字

Question

我对Python非常陌生，我正在尝试如何减去用户输入的数组中的数字。例如，在我的计划的早期，我有： `在

peakone = raw_input("Where is the next large peak?: ")
next_peak.append(peakone)
peaktwo = raw_input("Where is the next large peak?: ")
next_peak.append(peaktwo)

现在我要从peaktwo中减去peakone并将这个值保存为第三个值。如果有的话，最好的办法是什么？在

Answer 1

将next_peak设置为list

将输入转换为int或float

next_peak = []
peakone = raw_input("Where is the next large peak?: ")
next_peak.append(int(peakone))
peaktwo = raw_input("Where is the next large peak?: ")
next_peak.append(int(peaktwo))
print next_peak[0] - next_peak[1] 

如果需要，可以将int更改为float
