我從兩個串列中創建了一個字典。我正在嘗試更新存盤在字典中的值。我在 for 回圈中使用了 if 陳述句來過濾我想要修改的行，現在想要更改這些行的 dict 值。我想將帶有字串“Note Holder”的dict值更改為相應的姓氏“{Family Name} Family。所以我想用new_names（“空白”系列）更新字典中的名稱（Note Holder）。 這是我的代碼：
data = pd.read_excel('mailclean.xlsx')
ran = range(len(data))
tes = list(data.iloc[0:len(data)]['Column1'])
tes1 = list(data.iloc[0:len(data)]['Column2'])
dic = {}
for a in ran:
dic[tes[a]] = tes1[a]
for new_name in tes:
if "Family Trust" in new_name:
name = dic.get(new_name)
new_name = "The " new_name[:-6]
print(new_name)
print(name)
這是終端輸出：
The Guerland Family
Note Holder
The Sciammas Family

The Hsu Family

The Hemingway Family

The Williams Family

The Svancara Family

好的，正如所寫，您正在丟棄重要資訊。
for new_name in tes:
if "Family Trust" in new_name:
name = dic.get(new_name)
new_name = "The " new_name[:-6]
print(new_name)
print(name)
該new_name變數是您在字典中的唯一位置，并且您將其更改為其他內容，從而失去了您的位置。
更改持有密鑰的變數沒有任何意義。您想更改存盤在該鍵上的值，這只是另一個分配，與您最初用于將值放在那里的分配完全相同：
for name in dic:
if "Family Trust" in name:
dic[name] = "The " name[:-6]
實際上，您可以通過修改創建 dict 的原始回圈來完成它：
for a in ran:
if "Family Trust" in tes[a]:
dic[tes[a]] = "The " tes[a][:-6]
else:
dic[tes[a]] = tes1[a]

如果我理解正確，您首先創建了一個字典，其中鍵是陣列中的元素，tes值tes1在相應的陣列索引中。然后，您希望在給定特定條件（您的 if 陳述句）的情況下，將值（即 from tes1）從Note Holder更改為The {Family Name} Family?
也許是這樣的：
for name in tes:
if "Family Trust" in name:
new_name = "The " name[:-6]
dict[new_name] = new_name
鑒于我理解您的問題，您可以像這樣直接更新字典值。
