这让我困扰了好几个小时,而且我已经接近尾声了,我尝试了几种不同的变化,并且它以奇怪的方式出现。
我也发现了这个问题的不同时期,但是他们似乎都没有遇到我似乎遇到的问题。
问题/问题: 我可以在此代码下面的输出中看到。对于每个相应的行,计算没有跨越列,并且计算显然在行和列中保持相同的值,并且保持输出相同的值,35.7
代码:
def WindChill():
row = 0
col = 0
i = 0
wchill = round((35.74 + 0.6215*(col) - 35.75*(row**16) + 0.4275*(col)*(row**16)), 1)
print(10 * " ", "|", end = "")
head = -1
for i in range(1):
for col in range(-20, 70, 10):
print(3 * " ", col, "F", 3 * " ", "|", end = " ")
print("\n", 150 * "-")
while head < 0:
for row in range(0, 55, 5):
if (len(str(row))) < 2:
print(row, "mph", 4 * " ", "|", end = " ")
else:
print(row, "mph", 3 * " ", "|", end = " ")
print(3 * " ", round(wchill, 1), 3 * " ", "|", end = " ")
col = 0
head += 1
print("\n", 150 * "-")
print()
print()
输出:
| -20 F | -10 F | 0 F | 10 F | 20 F | 30 F | 40 F | 50 F | 60 F |
------------------------------------------------------------------------------------------------------------------------------------------------------
0 mph | 35.7 |

25 mph | 35.7 |
------------------------------------------------------------------------------------------------------------------------------------------------------
30 mph | 35.7 |
------------------------------------------------------------------------------------------------------------------------------------------------------
35 mph | 35.7 |
------------------------------------------------------------------------------------------------------------------------------------------------------
40 mph | 35.7 |
------------------------------------------------------------------------------------------------------------------------------------------------------
45 mph | 35.7 |
------------------------------------------------------------------------------------------------------------------------------------------------------
50 mph | 35.7 |
------------------------------------------------------------------------------------------------------------------------------------------------------
现在,显然,35.7的值应该是不同的,风速每增加5英里/小时,它应该计算每行的所有列的值。
表格和计算看起来应该类似于以下表格: http://www.nws.noaa.gov/os/windchill/index.shtml
答案 0 :(得分:2)
你在程序的最开始计算了wchill,当row = 0和col = 0.这个数字在开始时被评估为35.7,并且不会改变。
如果您希望wchill根据您当前打印的行/列进行更改,则需要调用该行
wchill = round((35.74 + 0.6215*(col) - 35.75*(row**16) + 0.4275*(col)*(row**16)), 1)
在打印之前,当行和列的值发生变化时。
编辑:我在这里要说的是,wchill本身并没有神奇地改变 - 你需要在每次行/列更改时重新计算它。

尽量减少非数据墨水!
def WindChillTable(of):
of.write(' -20\u00b0F')
for col in range(-10, 70, 10):
of.write('{: 6} '.format(col))
of.write('\n \u250c' + 71*'\u2500')
for row in range(0, 55, 5):
if row == 0:
of.write('\n mph 0 \u2502')
else:
of.write('\n {:2} \u2502'.format(row))
for col in range(-20, 70, 10):
of.write(' {: 5.1f} '.format(0))
of.write('\n')
if __name__ == '__main__':
import sys
WindChillTable(sys.stdout)

将此打印设为您想要的实际值,将其留作练习。
