设计一个python程序，计算人民币与其它货币之间汇率的兑换关系
两者为同向关系。人民币币值高则汇率也高。汇率是指本币与外币之间的比值。当人民币币值升高时，势必在同等汇率下，一定本币可以兑换外币，这就是人民币汇率高的表现。也就是说人民币币值高是汇率高的前提，汇率是币值的表现。

拓展资料
汇率是指一国货币与另一国货币的比率或比价，或者说是用一国货币表示的另一国货币的价格。汇率变动对一国进出口贸易有着直接的调节作用。在一定条件下，通过使本国货币对外贬值，即让汇率下降，会起到促进出口、限制进口的作用;反之,本国货币对外升值，即汇率上升,则起到限制出口、增加进口的作用。

求解答python，编写程序1元人民币换成1分、2分、5分有多少种方案，并展示出来是哪些方案
刚刚回答错了，分看成了角，下面是正确的
money = 1
count = 0
print('\t\t1分\t2分\t5分\(张)')
def jihua(money):
global count
for i in range(100):
for j in range(100):
for n in range(100):
if i * 0.01 + j * 0.02 + n * 0.05 == money:
count += 1
print('方案%d\t%d\t%d\t%d'
% (count, i, j, n))
jihua(money)
print('有%d种方案。' % count)
用python 怎么 解 将100元兑换为1元、5、10元的零钱，请问有多少种兑换方法？
cnt = 0
for i in xrange(100 / 1 + 1):
for j in xrange((100 - i * 1) / 5 + 1):
for k in xrange ((100 - i * 1 + j * 5) / 10 + 1):
if i * 1 + j * 5 + k * 10 == 100:
print "1:", i, "5:", j, "10:", k
cnt += 1
print cnt
结果如下，总共121种

用python程序设计美元和人民币转换
这种情况的话是完全没有任何问题的，你可以选择固定的公式进行计算，就完全可以达到一个好的效果。
python美元和人民币汇率
hunv=6.68
my=float(input("请输入美元的数量："))
print("%.2f美元可以兑换%.2f元的人名币"%(my,my*hunv))
