python - 如何将格式化的打印语句的输出插入到python中的数据框

问题描述

我有三个列表，我正在使用 f 字符串格式打印输出。

L = []
name = ['a', 'b', 'c']
dates = ['Jan', 'Feb', 'March']
event = ['Marriage', 'Office event', 'Birthday']
for a, b, c in zip(names, dates, event):
  print(f'I met {a} on {b} at this {c}')
  L.append(I met {a} on {b} at this {c})

我如何尝试将输出插入数据框：

df = pd.DataFrame(L, columns=['string_values'])

print (df)

解决方案

您已经得到了作为评论的指针，这是一个完整的答案：

df = pd.DataFrame({'string_values': [f'I met {a} on {b} at this {c}'
                                     for a, b, c in zip(names, dates, event)]
                   })

输出：

                         string_values
0      I met a on Jan at this Marriage
1  I met b on Feb at this Office event
2    I met c on March at this Birthday

使用您的（更正后的）原始代码：

L = []
names = ['a', 'b', 'c']
dates = ['Jan', 'Feb', 'March']
event = ['Marriage', 'Office event', 'Birthday']
for a, b, c in zip(names, dates, event):
    L.append(f'I met {a} on {b} at this {c}')
df = pd.DataFrame(L, columns=['string_values'])
