如何从txt文件制作字典？

Question

假设以下文本文件（dict.txt）有

1    2    3
aaa  bbb  ccc

字典应该是{1: aaa, 2: bbb, 3: ccc}像这样

我做了：

d = {}
with open("dict.txt") as f:
for line in f:
    (key, val) = line.split()
    d[int(key)] = val

print (d)

但它没有用。 我认为这是因为 txt 文件的结构。

Answer 1

你想成为键的数据在第一行，你想成为值的所有数据都在第二行。
所以，做这样的事情：

with open(r"dict.txt") as f: data = f.readlines() # Read 'list' of all lines

keys = list(map(int, data[0].split()))            # Data from first line
values = data[1].split()                          # Data from second line

d = dict(zip(keys, values))                       # Zip them and make dictionary
print(d)                                          # {1: 'aaa', 2: 'bbb', 3: 'ccc'}

基于 OP 编辑的更新答案：

#Initialize dict
d = {}

#Read in file by newline splits & ignore blank lines
fobj = open("dict.txt","r")
lines = fobj.read().split("\n")
lines = [l for l in line if not l.strip() == ""]
fobj.close()

#Get first line (keys)
key_list = lines[0].split()

#Convert keys to integers
key_list = list(map(int,key_list))

#Get second line (values)
val_list = lines[1].split()

#Store in dict going through zipped lists
for k,v in zip(key_list,val_list):
    d[k] = v

首先为键和值创建单独的列表，条件如下：

    if (idx % 2) == 0:
        keys = line.split()
        values = lines[idx + 1].split()

然后结合两个列表

d = {}

# Get all lines in list
with open("dict.txt") as f:
    lines = f.readlines()

for idx, line in enumerate(lines):
    if (idx % 2) == 0:
        # Get the key list
        keys = line.split()

        # Get the value list
        values = lines[idx + 1].split()

        # Combine both the lists in dictionary
        d.update({ keys[i] : values[i] for i in range(len(keys))})
print (d)
