python之在 csv 文件中打印多行输出

假设

A='First' 
B='Random' 
C='Degree' 
D='Largest' 
 
A='Second' 
B='Odd' 
C='Inclined' 
D='Maximum' 
 
A='Third' 
B='Even' 
C='Steep' 
D='Smallest' 
 
A='Fourth' 
B='Prime' 
C='Gradient' 
D='Minimum' 
 
c = ['Group', 'Number', 'Angle', 'Max value'] 
 
df = pd.DataFrame([[A, B, C, D]], columns=c) 
print (df) 
 
#to csv 
df.to_csv('Output.csv', encoding='utf-8', index=False) 
 

实际输出:

它只显示最后一个输出，而不是每个值。像这样，如果有 N 个值，csv 必须存储所有 N 个值，一个在另一个值下

Group  Number Angle    Max Value  
Fourth Prime  Gradient Minimum 

预期输出:

请您参考如下方法:

您应该遵循以下程序:

首先列出所有列，如下所示:

A = ['First', 'Random', 'Degree', 'Largest'] 
B = ['Second', 'Odd', 'Inclined', 'Maximum'] 
C = ['Third', 'Even', 'Steep', 'Smallest'] 
D = ['Fourth', 'Prime', 'Gradient', 'Minimum'] 

然后

c = ['Group', 'Number', 'Angle', 'Max value'] 
df = pd.DataFrame([A, B, C, D], columns=c) 
print (df) 
 
#to csv 
df.to_csv('Output.csv', encoding='utf-8', index=False) 

输出:

    Group  Number     Angle Max value 
0   First  Random    Degree   Largest 
1  Second     Odd  Inclined   Maximum 
2   Third    Even     Steep  Smallest 
3  Fourth   Prime  Gradient   Minimum
