以表格格式打印字典的Python程序

给定一个字典。任务是以表格格式打印字典。
例子：

Input: 
{1: [“Samuel”, 21, ‘Data Structures’], 
2: [“Richie”, 20, ‘Machine Learning’], 
3: [“Lauren”, 21, ‘OOPS with java’], 
}
Output: 
NAME AGE COURSE 
Samuel 21 Data Structures 
Richie 20 Machine Learning 
Lauren 21 OOPS with java 
 

方法1：通过值迭代显示结果。

Python3

# Define the dictionary
dict ={}
 
# Insert data into dictionary
dict1 = {1: ["Samuel", 21, 'Data Structures'],
     2: ["Richie", 20, 'Machine Learning'],
     3: ["Lauren", 21, 'OOPS with java'],
     }
 
# Print the names of the columns.
print ("{:<10} {:<10} {:<10}".format('NAME', 'AGE', 'COURSE'))
 
# print each data item.
for key, value in dict1.items():
    name, age, course = value
    print ("{:<10} {:<10} {:<10}".format(name, age, course))

输出：

NAME       AGE        COURSE    
Samuel     21         Data Structures
Richie     20         Machine Learning
Lauren     21         OOPS with java

方法二：使用矩阵格式显示

Python3

# define the dictionary
dict1 = {}
 
# insert data into dictionary
dict1 = {(0, 0): 'Samuel', (0, 1): 21, (0, 2): 'Data structures',
         (1, 0): 'Richie', (1, 1): 20, (1, 2): 'Machine Learning',
         (2, 0): 'Lauren', (2, 1):21, (2, 2): 'OOPS with Java'
}
 
# print the name of the columns explicitly.
print(" NAME ", " AGE ", "  COURSE " )
 
# Iterate through the dictionary
# to print the data.
for i in range(3):
     
    for j in range(3):
        print(dict1[(i, j)], end ='   ')
         
    print()

输出：

NAME   AGE    COURSE 
Samuel   21   Data structures   
Richie   20   Machine Learning   
Lauren   21   OOPS with Java 

方法3：使用zip格式显示

Python3

# define the dictionary
dict1 = {}
 
# insert data into dictionary.
dict1 = {'NAME':['Samuel', 'Richie', 'Lauren'],
         'AGE':[21, 20, 21],
         'COURSE':['Data Structures', 'Machine Learning', 'OOPS with Java']}
 
# print the contents using zip format.
for each_row in zip(*([i] + (j)
                      for i, j in dict1.items())):
     
      print(*each_row, " ")

输出：

NAME  AGE COURSE  
Samuel 21 Data Structures  
Richie 20 Machine Learning  
Lauren 21 OOPS with Java
