我有一个文本文件,看起来像这样:

Monstera Deliciosa
2018-11-03 18:21:26
Tropical/sub-Tropical plant
Leathery leaves, mid to dark green
Moist and well-draining soil
Semi-shade/full shade light requirements
Water only when top 2 inches of soil is dry
Intolerant to root rot
Propagate by cuttings in water

Strelitzia Nicolai (White Birds of Paradise)
2018-11-05 10:12:15
Semi-shade, full sun
Dark green leathery leaves
Like lots of water,but soil cannot be water-logged
Like to be root bound in pot

Alocasia Macrorrhizos
2019-01-03 15:29:10
Tropical asia
Moist and well-draining soil
Leaves and stem toxic upon ingestion
Semi-shade, full sun
Like lots of water, less susceptible to root rot
Susceptible to spider mites

我想用这个文件创建一个字典,其中植物的名称作为字典的键,其余信息作为值放在一个列表中。到目前为止,我已经设法将每种植物及其各自的信息作为列表中的一个项目,但我不知道如何将其转换为字典

    with open('myplants.txt', 'r') as f:
        contents = f.read()
        contents = contents.rstrip().split('\n\n')
        contents = [x.replace('\n', ', ') for x in contents]
    print(contents)#[0].split(',',0)[0])

预期产出:

plants = {'Monstera Deliciosa':['2018-11-03 18:21:26', 'Tropical/sub-Tropical plant', 'Leathery leaves, mid to dark green', 'Moist and well-draining soil', 'Semi-shade/full shade light requirements', 'Water only when top 2 inches of soil is dry', 'Intolerant to root rot', 'Propagate by cuttings in water'], 'Strelitzia Nicolai (White Birds of Paradise)': ... }

我对更好的字典格式持开放态度

像这样的东西行吗

plants = {}
with open('myplants.txt', 'r') as f:
    contents = f.read()
    contents = contents.rstrip().split('\n\n')
    for content in contents:
      parts = content.split('\n') # Convert the lines to a list of strings
      plants[ parts[0] ] = parts[1:] # first line becomes key, the rest become the values
print(plants)

使用字典理解:

text = """Monstera Deliciosa
2018-11-03 18:21:26
Tropical/sub-Tropical plant
Leathery leaves, mid to dark green
Moist and well-draining soil
Semi-shade/full shade light requirements
Water only when top 2 inches of soil is dry
Intolerant to root rot
Propagate by cuttings in water

Semi-shade, full sun

"""

contents = text.rstrip().split('\n\n')
contents = [x.replace('\n', ', ') for x in contents]

plants = {c.split(',')[0]: c.split(',')[1:]
          for c in contents}

print(plants)

返回:

{'Monstera Deliciosa': [' 2018-11-03 18:21:26', ' Tropical/sub-Tropical plant', ' Leathery leaves', ' mid to dark green', ' Moist and well-draining soil', ' Semi-shade/full shade light requirements', ' Water only when top 2 inches of soil is dry', ' Intolerant to root rot', ' Propagate by cuttings in water'], 'Strelitzia Nicolai (White Birds of Paradise)': [' 2018-11-05 10:12:15', ' Semi-shade', ' full sun', ' Dark green leathery leaves', ' Like lots of water', 'but soil cannot be water-logged', ' Like to be root bound in pot'], 'Alocasia Macrorrhizos': [' 2019-01-03 15:29:10', ' Tropical asia', ' Moist and well-draining soil', ' Leaves and stem toxic upon ingestion', ' Semi-shade', ' full sun', ' Like lots of water', ' less susceptible to root rot', ' Susceptible to spider mites']}

这是一个可扩展的解决方案,可以避免在内存中读取整个文件

它利用了一个事实,即文本文件可以用作产生每一行的迭代器

import itertools as it

plants = {}
with open('myplants.txt') as f:
    while True:
        try:
            p = next(f).rstrip()
            plants[p] = list(l.rstrip() for l in it.takewhile(lambda line: line != '\n', f))
        except StopIteration:
            break

print(plants)

产生

{
 'Monstera Deliciosa': ['2018-11-03 18:21:26', 'Tropical/sub-Tropical plant', 'Leathery leaves, mid to dark green', 'Moist and well-draining soil', 'Semi-shade/full shade light requirements', 'Water only when top 2 inches of soil is dry', 'Intolerant to root rot', 'Propagate by cuttings in water'],
 'Strelitzia Nicolai (White Birds of Paradise)': ['2018-11-05 10:12:15', 'Semi-shade, full sun', 'Dark green leathery leaves', 'Like lots of water,but soil cannot be water-logged', 'Like to be root bound in pot'],
 'Alocasia Macrorrhizos': ['2019-01-03 15:29:10', 'Tropical asia', 'Moist and well-draining soil', 'Leaves and stem toxic upon ingestion', 'Semi-shade, full sun', 'Like lots of water, less susceptible to root rot', 'Susceptible to spider mites']
}
