嘗試連接 2 個串列中的專案并將它們作為字串輸出。但是，收到此錯誤 - 只能將 str（而不是“串列”）連接到 str
forenames = ['homer','bart','lisa']
surname = ['simpson']
fullnames =[]
for name in forenames:
fullnames.append(name ' ' surname)
print (fullnames)

您可以通過以下方式進行操作：
forenames = ['homer','bart','lisa']
surname = ['simpson']
for forename in forenames:
print(forename ' ' surname[0])
輸出如下所示：
homer simpson
bart simpson
lisa simpson

你在尋找這樣的東西嗎？
forenames = ['homer','bart','lisa']
surname = ['simpson']
fullnames =[]
for name in forenames:
fullnames.append(name ' ' surname[0])
print ("\n".join(fullnames))
輸出：
homer simpson
bart simpson
lisa simpson
uj5u.com熱心網友回復：
您可以使用嵌套回圈來組合元素：
forenames = ['homer','bart','lisa']
surnames = ['simpson', 'burns']
fullnames = [f"{fname} {sname}" for fname in forenames for sname in surnames]
print(fullnames) # ['homer simpson', 'homer burns', 'bart simpson', 'bart burns', 'lisa simpson', 'lisa burns']
串列理解部分相當于
fullnames = []
for fname in forenames:
for sname in surnames:
fullnames.append(f"{fname} {sname}")
uj5u.com熱心網友回復：
forenames = ['homer','bart','lisa']
surname = ['simpson']
for f in forenames:
for s in surname:
fullnames = [f'{f} {s}']
str_fullnames = ''
print(str_fullnames.join(fullnames))
