Question

我有一个这样的文件：

group #1
a b c d
e f g h

group #2
1 2 3 4
5 6 7 8

我怎样才能把它变成这样的字典：

{'group #1' : [[a, b, c, d], [e, f, g, h]], 
 'group #2' :[[1, 2, 3, 4], [5, 6, 7, 8]]}

Answer 1

file = open("file","r")                       # Open file for reading 
dic = {}                                      # Create empty dic

for line in file:                             # Loop over all lines in the file
        if line.strip() == '':                # If the line is blank
            continue                          # Skip the blank line
        elif line.startswith("group"):        # Else if line starts with group
            key = line.strip()                # Strip whitespace and save key
            dic[key] = []                     # Initialize empty list
        else:
            dic[key].append(line.split())     # Not key so append values

print dic

输出：

{'group #2': [['1', '2', '3', '4'], ['5', '6', '7', '8']], 
 'group #1': [['a', 'b', 'c', 'd'], ['e', 'f', 'g', 'h']]}

Answer 2

迭代文件，直到找到“group”标记。使用该标记向字典添加新列表。然后将行添加到该标记，直到您点击另一个“组”标记。

未测试

d = {}
for line in fileobject:
    if line.startswith('group'):
        current = d[line.strip()] = []
    elif line.strip() and d:
        current.append(line.split())
