Question

我有一本字典，我不知道如何将提取的变量存储回我的字典中，以便我可以返回字典。

data = """Amanda:100
Katie:90
Eric:78
Mike:45
Paul:71"""

这是给出的数据。

# write a function parseData() which:
#      parses the initial data (data),
#      stores them in a dictionary, and
#      returns the dictionary to the caller.
#      The student name must be the key of the dictionary, and
#      the student grade  its corresponding value

我创建了这个函数并添加了空字典。

def parseData():

# Initialize an empty dictionary.
    students = dict()

#  After initializing the dictionary, scan all the lines of the data string provided.
    infos = data.split('\n')
    print infos

#  For each line that you get, extract the student and the student scores from that line and
#  store it in a two variables: name and scores
    for info in infos:
        names = info.split(':')
        print names
        name = names[0]
        score = names[1]
        print score
        students[name] = score

这是我被困的地方。为了存储变量，我想把它放在：

#   Store the extracted variables name and scores in the dictionary initialized in and
#   return that dictionary
    students[info] = score()[info]
    return students

您可以像这样使用dict构造函数

print dict(line.split(":") for line in data.splitlines())
# {'Paul': '71', 'Mike': '45', 'Amanda': '100', 'Eric': '78', 'Katie': '90'}

这可以写成

result = {}
for line in data.splitlines():
    splitted_values = line.split(":")
    result[splitted_values[0]] = splitted_values[1]
print result

将提取的变量存储到字典中
