我有描述具體參數列的列表中的文件:從該文件在表中匹配行號與字符串。
尺寸大小亮度
我只需要特定的數據(尤其是行和列)。到目前爲止,我在python中有一個代碼,我在其中附加了必要的行號。我只需要知道我如何匹配它以獲取文本文件中的正確字符串以及列(量級)和(光度)中的變量。關於如何處理這個問題的任何建議?
這裏是我的代碼示例(#comments形容我做了什麼什麼,我想做的事):
temp_ListMatch = (point[5]).strip()
if temp_ListMatch:
ListMatchaddress = (point[5]).strip()
ListMatchaddress = re.sub(r'\s', '_', ListMatchaddress)
ListMatch_dirname = '/projects/XRB_Web/apmanuel/499/Lists/' + ListMatchaddress
#print ListMatch_dirname+"\n"
try:
file5 = open(ListMatch_dirname, 'r')
except IOError:
print 'Cannot open: '+ListMatch_dirname
Optparline = []
for line in file5:
point5 = line.split()
j = int(point5[1])
Optparline.append(j)
#Basically file5 contains the line numbers I need,
#and I have appended these numbers to the variable j.
temp_others = (point[4]).strip()
if temp_others:
othersaddress = (point[4]).strip()
othersaddress =re.sub(r'\s', '_', othersaddress)
othersbase_dirname = '/projects/XRB_Web/apmanuel/499/Lists/' + othersaddress
try:
file6 = open(othersbase_dirname, 'r')
except IOError:
print 'Cannot open: '+othersbase_dirname
gmag = []
z = []
rh = []
gz = []
for line in file6:
point6 = line.split()
f = float(point6[2])
g = float(point6[4])
h = float(point6[6])
i = float(point6[9])
# So now I have opened file 6 where this list of data is, and have
# identified the columns of elements that I need.
# I only need the particular rows (provided by line number)
# with these elements chosen. That is where I'm stuck!
也許我失去了一些東西,但爲什麼不增加你檢查每一個新行的數字?你可以在添加行的內容時使用該行索引字典,決定是否需要行,等等。 – Patashu 2013-03-18 03:31:42
我正確地認爲你有一個文件包含格式爲'size magnitude luminosity'的行,而另一個文件與行號列表?而且,您只想提取指定行的大小和亮度列? – 2013-03-18 04:27:27
什麼是「點」?它拿着什麼? – pradyunsg 2013-03-18 04:55:22
