| | | |

方法:使用 + 運算符 + 列表推導

在這個任務中,我們只需使用+ 運算符,列表推導用於遍歷所有元素。


< td class = "code">

# Python3 代碼演示它是如何工作的
# 在行中添加後綴/前綴list
# 使用推導式列表 + 運算符 & quot; + & quot;


# 初始化列表

test_list = [ `a` , `b` , `c` , `d` ]


# 打印列表

print ( "原始列表:" + str (test_list))


# 初始化 append_str

append_str = `gfg`


# 給列表中的行添加後綴/前綴

pre_res = [append_str + sub for sub in test_list]

suf_res = [sub + append_str for sub in test_list]


# 打印結果

print ( "前綴添加後的列表on:" + str (pre_res))

print ( "後綴添加後的列表:" + str (suf_res))

輸出:

原始列表:[`a`, `b`,`c`, `d`] 前綴添加後的列表:[`gfga` , `gfgb`,`gfgc`, `gfgd`] 列表後綴加法:[`agfg`, `bgfg`,`cgfg`,`dgfg`]
