我有一个熊猫数据框df_causation
,我已将其创建为具有相应列名称的空数据框。
df_causation = pd.DataFrame(columns=['Question'])
我有一个for
循环,在该循环中,每次循环都会得到一个名为cause_str
的新字符串,如下所示:-
for i in range(len(X_test)):
cause_str = hyp.join(f_imp) #cause_str is a new string obtained for each iteration
(忽略获取方法,我只是举了一个例子)
我想将这些新字符串(cause_str)
(全部)添加到每个连续的行在我的Pandas数据帧df_causation
的“问题”列中。有合适的方法吗?
编辑:预期输出
df_causation. **Causation**
Row 0 cause_str from i = 0 th iteration in loop
Row 1 cause_str from i = 1 th iteration in loop etc.
IIUC正确,这应该起作用:
dfd['**Causation**'] = df['df_causation.'].apply(lambda x: f'cause str from i = {x.split(" ")[1]} th iteration in loop')
df3
df_causation. **Causation**
0 Row 0 cause str from i = 0 th iteration in loop
1 Row 1 cause str from i = 1 th iteration in loop
