Hướng dẫn python tabulate nested dictionary - python lập bảng từ điển lồng nhau

Your problem seems to reach any of the datastructure needed for 

Name    School         Class         Teacher
------  -------------  ------------  --------------
Tom     school_name_1  class_name_1  teachers_name1
Jerry   school_name_2  class_name_2  teachers_name2
68. The easier seems to be the one where 
Name    School         Class         Teacher
------  -------------  ------------  --------------
Tom     school_name_1  class_name_1  teachers_name1
Jerry   school_name_2  class_name_2  teachers_name2
69 defines a list of column headers and the data is a 2D list of values

Using a 

Name    School         Class         Teacher
------  -------------  ------------  --------------
Tom     school_name_1  class_name_1  teachers_name1
Jerry   school_name_2  class_name_2  teachers_name2
70 and flattening the values of each inner dict, that's quite simple:

from tabulate import tabulate

headers = ["Name", "School", "Class", "Teacher"]
values = {"Tom": {"SchoolName1": "school_name_1", "Classname1": "class_name_1", "teacher1": "teachers_name1"},
          "Jerry": {"SchoolName2": "school_name_2", "Classname2": "class_name_2", "teacher2": "teachers_name2"}}

values = [[name, *inner.values[]] for name, inner in values.items[]]

print[tabulate[values, headers=headers]]

Giving the expected

Name    School         Class         Teacher
------  -------------  ------------  --------------
Tom     school_name_1  class_name_1  teachers_name1
Jerry   school_name_2  class_name_2  teachers_name2

Đây là phiên bản cập nhật của câu trả lời của tôi trong đó các cấu trúc dữ liệu của cây hiện khác với các phiên bản còn lại của nó. Thay vì cây hoàn toàn là một ____ 7 lồng-lồng -____ 7, "lá" trên mỗi nhánh hiện là trường hợp của một lớp con khác nhau của 

Name    School         Class         Teacher
------  -------------  ------------  --------------
Tom     school_name_1  class_name_1  teachers_name1
Jerry   school_name_2  class_name_2  teachers_name2
71 có tên 

abc/pqr/lmn/xyz:pass
abc/pqr/lmn/bcd:pass
abc/pqr/lmn/xyz:fail
abc/pqr/lmn/xyz:pass
0 rất hữu ích cho việc đếm số lần mỗi khóa của chúng xảy ra. Tôi đã làm điều này vì câu trả lời của bạn cho câu hỏi của tôi về điều gì sẽ xảy ra nếu phần cuối cùng của mỗi dòng là một thứ khác ngoài 
abc/pqr/lmn/xyz:pass
abc/pqr/lmn/bcd:pass
abc/pqr/lmn/xyz:fail
abc/pqr/lmn/xyz:pass
1 [đó là "chúng ta phải đặt số lượng mới cho khóa đó"].

  • Làm thế nào để bạn tạo ra một từ điển động trong Python?
  • Làm thế nào để bạn tạo ra một từ điển lồng nhau trong Python?
  • Một từ điển có thể được lồng trong Python?
  • Làm thế nào để bạn thêm nhiều từ điển trong Python?

Từ điển lồng nhau thường được gọi là cấu trúc dữ liệu 

abc/pqr/lmn/xyz:pass
abc/pqr/lmn/bcd:pass
abc/pqr/lmn/xyz:fail
abc/pqr/lmn/xyz:pass
2 và có thể được xác định đệ quy-gốc là một từ điển như các nhánh. Sau đây sử dụng lớp con 
Name    School         Class         Teacher
------  -------------  ------------  --------------
Tom     school_name_1  class_name_1  teachers_name1
Jerry   school_name_2  class_name_2  teachers_name2
71 thay vì đơn giản 
Name    School         Class         Teacher
------  -------------  ------------  --------------
Tom     school_name_1  class_name_1  teachers_name1
Jerry   school_name_2  class_name_2  teachers_name2
71 vì nó giúp việc xây dựng chúng trở nên dễ dàng hơn vì bạn không cần phải tạo ra một trường hợp tạo ra nhánh đầu tiên của cấp độ tiếp theo [ngoại trừ tôi vẫn làm khi thêm "lá" vì chúng là một lớp con khác, 
abc/pqr/lmn/xyz:pass
abc/pqr/lmn/bcd:pass
abc/pqr/lmn/xyz:fail
abc/pqr/lmn/xyz:pass

Để kiểm tra các khả năng đếm lá của mã sửa đổi, tôi đã sử dụng tệp thử nghiệm sau bao gồm cùng một dòng hai lần, một lần kết thúc lại với 

abc/pqr/lmn/xyz:pass
abc/pqr/lmn/bcd:pass
abc/pqr/lmn/xyz:fail
abc/pqr/lmn/xyz:pass
6 và một kết thúc khác trong 
abc/pqr/lmn/xyz:pass
abc/pqr/lmn/bcd:pass
abc/pqr/lmn/xyz:fail
abc/pqr/lmn/xyz:pass
7.

Mở rộng tệp kiểm tra 

abc/pqr/lmn/xyz:pass
abc/pqr/lmn/bcd:pass
abc/pqr/lmn/xyz:fail
abc/pqr/lmn/xyz:pass
8:
abc/pqr/lmn/xyz:pass
abc/pqr/lmn/bcd:pass
abc/pqr/lmn/xyz:fail
abc/pqr/lmn/xyz:pass

Output:

Điều kiện tiên quyết - Từ điển Python trong Python hoạt động tương tự như từ điển trong thế giới thực. Các khóa của từ điển phải là duy nhất và loại dữ liệu bất biến như chuỗi, số nguyên và bộ dữ liệu, nhưng các giá trị khóa có thể được lặp lại và thuộc bất kỳ loại nào. Từ điển: Từ điển làm tổ có nghĩa là đặt một từ điển vào từ điển khác. Nesting được sử dụng rất nhiều vì loại thông tin chúng ta có thể mô hình hóa trong các chương trình được mở rộng rất nhiều. & NBSP; & NBSP;Python dictionaryA Dictionary in Python works similar to the Dictionary in the real world. Keys of a Dictionary must be unique and of immutable data type such as Strings, Integers and tuples, but the key-values can be repeated and be of any type.Nested Dictionary: Nesting Dictionary means putting a dictionary inside another dictionary. Nesting is of great use as the kind of information we can model in programs is expanded greatly.  Python dictionary
