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`]
