我具有以下结构,我想将其写入指定宽度的文件中,有趣的是我无法使其正常工作。
{'c': {' eva X': -15,
'Cki Xi': -2,
'I Xalt': -23,
'Ik Xip': -8,
'Ir 1 X': -19,
'Xamdal': 20,
'Xincik': 11,
'bu aXa': -1,
'elinde Xop': -24,
'gol aX': 5,
'huyu X': -6,
'ie Xol': -14,
'im teX': -16,
'k Xipl': 18,
'kriz X': 17,
'm Xars': 7,
'mUS aX': -13,
'mem Xi': -21,
'na Xog': 3,
'ncu X ': 9,
'ram Xo': 4,
'tI Xat': 22,
'vre aX': 12,
'zay Xo': 10}}
结果应如下所示((ps:顺序可能有所不同)
{'c': {"bu aXa": -1, "Cki Xi": -2, "na Xog": 3,
"ram Xo": 4, "gol aX": 5, "huyu X": -6,
"m Xars": 7, "Ik Xip": -8, "ncu X ": 9,
"zay Xo": 10, "Xincik": 11, "vre aX": 12,
"mUS aX": -13, "ie Xol": -14, " eva X": -15,
"im teX": -16, "kriz X": 17, "k Xipl": 18,
"Ir 1 X": -19, "Xamdal": 20, "mem Xi": -21,
"tI Xat": 22, "I Xalt": -23, "elinde Xop": -24}}
我尝试了pprint
,但没有成功。我无法获得理想的结果。
import pprint
pprint.pprint(data, width=100)
pprint.pprint(data, width=200)
pprint.pprint(data, width=300)
# {'c': {' eva X': -15,
# 'Cki Xi': -2,
# 'I Xalt': -23,
# 'Ik Xip': -8,
# 'Ir 1 X': -19,
# 'Xamdal': 20... (all of them same as above)

在pprint的文档中说-
使用width参数来限制所需的输出宽度;默认值为80个字符。如果无法在限制的宽度内格式化结构,则将尽力而为。如果compact为false(默认设置),则长序列的每个项目都将在单独的行上格式化。如果compact为true,则将在每条输出行上格式化所有适合宽度的项目。
因此,可以将compact=True
参数用于所需的输出。但是您需要找到压缩宽度的大致宽度,如您所愿,将三个key:value压缩在一行中。

这是我建议使用纯Python的解决方案。包含注释是为了帮助理解我的逻辑:
indict = {'c': {' eva X': -15,
'Cki Xi': -2,
'I Xalt': -23,
'Ik Xip': -8,
'Ir 1 X': -19,
'Xamdal': 20,
'Xincik': 11,
'bu aXa': -1,
'elinde Xop': -24,
'gol aX': 5,
'huyu X': -6,
'ie Xol': -14,
'im teX': -16,
'k Xipl': 18,
'kriz X': 17,
'm Xars': 7,
'mUS aX': -13,
'mem Xi': -21,
'na Xog': 3,
'ncu X ': 9,
'ram Xo': 4,
'tI Xat': 22,
'vre aX': 12,
'zay Xo': 10}}
#Create a string from dict.
dictString = str(indict)
#Set the number of elements you want for each row.
elements = 3
#Split the string to individual records of dict.
dictString = dictString.split(',')
#Add ' ,' to the end.
newString = list(map(lambda i: i+" ,", dictString[:-1]))
newString.append(dictString[-1])
#Find the position of the dict 'opening' bracket in order to be used as padding point.
pos = newString[0].find(": {") + 2
print(pos)
#Form row with number of elements defined by the 'elements' variable.
newString = ["".join(newString[i:i+elements]) for i in range(0,len(newString),elements)]
#Pad each row to match with the padding point.
newString = [newString[0]] + [i.rjust(len(i) + pos,' ') for i in newString[1:]]
#Create a final string, appending all rows.
finalString = "\n".join(newString)
print(finalString)
#Write the string to file.
with open("output.txt", "w") as outFile:
outFile.write(finalString)
print(finalString)
的输出:
{'c': {' eva X': -15 , 'Cki Xi': -2 , 'I Xalt': -23 ,
'Ik Xip': -8 , 'Ir 1 X': -19 , 'Xamdal': 20 ,
'Xincik': 11 , 'bu aXa': -1 , 'elinde Xop': -24 ,
'gol aX': 5 , 'huyu X': -6 , 'ie Xol': -14 ,
'im teX': -16 , 'k Xipl': 18 , 'kriz X': 17 ,
'm Xars': 7 , 'mUS aX': -13 , 'mem Xi': -21 ,
'na Xog': 3 , 'ncu X ': 9 , 'ram Xo': 4 ,
'tI Xat': 22 , 'vre aX': 12 , 'zay Xo': 10}}
文件内容相同。

这是我为自己的问题写的解决方案,根据我的需要进行了一些修改。我仍然愿意接受想法。不幸的是,pprint
涵盖了这种情况。
def prettyPrint(myDict, itemPerLine=3):
myStr = '{'
for k1, v1 in myDict.items():
myStr += "'" + k1 + "': {"
itemCount = 0
for k2, v2 in v1.items():
myStr += '"' + str(k2) + '": ' + str(v2) + ', '
if itemCount == itemPerLine:
myStr += '\n' + ' ' * 32
itemCount = 0
itemCount += 1
myStr = myStr[:-2] + "},\n" + ' ' * 26
return myStr[:-2] + "}"
prettyPrint(data)
