は、文字列のリストは、リストのPythonで

Question

のリストに変換する方法をどのように変換します：

list a = [ 'i am going to America', 'i will come by tomorrow evening' ] 

    into 

list b = [ [i am going to America], [i will come by tomorrow evening] ] 

Answer 1

使用リストの内包を。

>>> a = [ 'i am going to America', 'i will come by tomorrow evening' ] 
>>> [[x] for x in a] 
[['i am going to America'], ['i will come by tomorrow evening']] 

Answer 2

あなたはリスト内包表記を使用して、あなたがリストとして各エントリを宣言しmain_list

list = ['i am going'] 
main_list.append(list) 

にそれを追加する必要があり、別のリスト

list_a = [ 'i am going to America', 'i will come by tomorrow evening' ] 
print(list_a) # ['i am going to America', 'i will come by tomorrow evening'] 

list_b = [[x] for x in list_a] 
print(list_b) # [['i am going to America'], ['i will come by tomorrow evening']] 

Answer 3

を生成することができますが、これを試してみてください。

list = ['iam g', 'here'] 
main_list = [] 
main_list.append(list) 
print main_list 
output: [['iam g', 'here']] 
main_list.append(list) 
print main_list 
output: [['iam g', 'here'], ['iam g', 'here']]
