python - 在 csv 文件中打印多行输出

Question

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:

Answer 1

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
