從字符串中刪除“

Question

with open("p022_names.txt","r") as f:
    for line in f:
        name=[str(v) for v in line.split(",")]
name.sort()
print(name)
tot=0
for i in range(len(name)):
    tot=tot+sum(ord(letter)-64 for letter in name[i])
print(tot)

從文件讀取數據時，還會在名稱中添加“和”。如果名稱為COLIN，則將其另存為列表名稱為““ COLIN”'。如何解決？輸入文件。

輸出['“ MARY”'，'“ ...”'，'“ ...”'，..]

Answer 1

如果要從字符串中刪除這些字符，則可以執行以下操作：

s = s.replace("\\"","")

這將用空字符串替換所有的"實例。

如果只希望在字符串的末尾刪除它們，則可以執行此操作

s = s.strip("\\"")

如果您想確保只在兩端刪除一個引號，則可以執行以下操作：

if s.startswith("\""):
    s = s[1:]
elif s.endswith("\""):
    s = s[:-1]

如果您知道字符串將始終帶有引號，則可以將其簡化為：

s = s[1:-1]

但是，此文件似乎是一個csv文件，最好使用csv lib解析這些文件。

Answer 2

您可以通過以下方式從Python字符串中刪除開頭和結尾字符：

name = "'COLIN'"
print(name[1:-1])

這將打印COLIN而不是'COLIN'

Answer 3

這是我的解決方案。 它支持以逗號分隔的多行名稱，也支持文件中的多行名稱。

names = []
with open('p022_names.txt') as f:
    for line in f:
        names.extend(v.lower().strip('"').strip("'") for v in line.split(","))

names.sort()

for name in names:
    tot = sum(ord(letter)-96 for letter in name)
    print("{0}: {1}".format(name, tot))

Answer 4

with open("p022_names.txt","r") as f:
    for line in f:
        name=[str(v) for v in line.split(",")]
name.sort()
print(name)

我假設您看到的是這樣的：

['"MARY"','"PATRICIA"'...]

如果我正確理解了您的問題，則希望同時刪除'和teh "字符。此處的'字符表示列表中的元素是字符串。 您的實際數據中沒有任何這些。您只需要去除雙引號。你不必擔心單引號。你唯一的報價是"那些從文件中讀取的。

另外，您可以簡化

name=[str(v) for v in line.split(",")]

至

name = line.split(",")
