打印清單表

Question

我有一段代碼

resultDict = {} 
for startCity in places: 
    for endCity in places: 
     startLocation = startCity[0] + ' ' + startCity[1] 
     endLocation = endCity[0] + ' ' + endCity[1] 
     resultLocations = [startLocation, endLocation] 
     resultId = ','.join(resultLocations.sort()) 

     if startLocation == endLocation or resultId in resultDict: 
      continue 

     dlat = math.radians(float(startCity[2])-float(endCity[2])) 
     dlon = math.radians(float(startCity[3])-float(endCity[3])) 
     a = math.sin(dlat/2) * math.sin(dlat/2) + math.cos(math.radians(float(endCity[2]))) \ 
      * math.cos(math.radians(float(startCity[2]))) * math.sin(dlon/2) * math.sin(dlon/2) 
     c = 2 * math.atan2(math.sqrt(a), math.sqrt(1-a)) 
     d = radius * c 
     resultDict[resultId] = d * 0.621371 

print resultDict 

使用print語句時產生以下屏幕：

(0.0, (['Millersville CA'], ['Millersville CA']), 0.0) 
(1626.614065545485, (['Millersville CA'], ['Millersville IL']), 1616.3457942569537)

(143.7059918008934, (['Millersville IL'], ['Millersville MO']), 144.75572344683556) 

它是什麼做的是計算一堆之間的距離城市，然後產生結果作爲英里的距離的列表中，那麼這兩個城市的名稱，然後這兩個城市作爲一種檢查之間的勾股定理距離。我怎麼會去格式化打印語句打印結果出來是這樣的：

我想這是打印出來的屏幕上，所以我將如何去使用print和正確地在格式化它將列標題作爲城市，然後爲英里輸入正確的號碼？

我想到的是這個代碼並不完全符合我的要求......它只吐出第一對城市，然後移動到下一對，並將它們打印在第一對下方：

print "\n\n    {0:^}".format(resultDict2),"\n\n{0:^}".format(resultDict3)," {0:^12.5}".format(resultDict4),"\nGC   {0:^22.5}".format(resultDict1) 

這裏的印結的幾個例子：

   Millersville MI 

Millersville TN  553.22  
GC     549.55   


      Millersville MI 

Millersville WV  434.49  
GC     433.64   


      Millersville MI 

Millersville MI  0.0  
GC     0.0 

有沒有辦法讓代碼打印下一對城市的最後一權，而不是樓下？

我欣賞的幫助......我一直停留在這過去幾天，似乎無法得到它的工作。

Answer 1

首先，我會解決你的數據結構（它有點搞砸）

resultDict = {} 
cities = [' '.join(c[:2]) for c in places] 
for startCity in places: 
    for endCity in places: 
     start = ' '.join(startCity[:2]) 
     end = ' '.join(endCity[:2]) 
     resultDict[start, end] = calc_distance(startCity, endCity) 

凡calc_distance返回一個列表（正常和GC）的兩個距離。像

def calc_distance(startCity, endCity): 
    # whatever magic you need to do to calculate your distances 
    return [distance, gc_distance] 

現在resultDict應該像

{ 
    ('Millersville CA', 'Millersville CA'): [0.0, 0.0], 
    ('Millersville CA', 'Millersville IL'): [1616.3457942569537, 1626.614065545485], 
    ('Millersville CA', 'Millersville IN'): [1778.7968284940225,1789.8845362720158], 
    ('Millersville CA', 'Millersville MD'): [2281.198586905769,2295.8829666956335], 
    ('Millersville CA', 'Millersville MO'): [1584.3029694701652, 1595.039113682296], 
    ('Millersville CA', 'Millersville NC'): [2068.1505623183266, 2082.089905489436], 
    .... 
} 

然後打印出來是沒有意義的你的工作更容易

print "\n" 
f = "{:>22}" * (len(cities) + 1) 
print f.format("", *cities) 
for c in cities: 
    print 
    print f.format(c, *[resultDict.get((c, e))[0] for e in cities]) 
    print f.format("[GC]", *[resultDict.get((c, e))[1] for e in cities])
