从字符串中删除“

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)

从文件读取数据时，还会在名称中添加“和”。如果名称为COLIN，则将其另存为列表名称为““ COLIN”'。如何解决？输入文件。

输出['“ MARY”'，'“ ...”'，'“ ...”'，..]

Answer 1

如果要从字符串中删除这些字符，则可以执行以下操作：

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

这将用空字符串替换所有的"实例。

如果只希望在字符串的末尾删除它们，则可以执行此操作

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

如果您想确保只在两端删除一个引号，则可以执行以下操作：

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

如果您知道字符串将始终带有引号，则可以将其简化为：

s = s[1:-1]

但是，此文件似乎是一个csv文件，最好使用csv lib解析这些文件。

Answer 2

您可以通过以下方式从Python字符串中删除开头和结尾字符：

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

这将打印COLIN而不是'COLIN'

Answer 3

这是我的解决方案。 它支持以逗号分隔的多行名称，也支持文件中的多行名称。

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)

我假设您看到的是这样的：

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

如果我正确理解了您的问题，则希望同时删除'和teh "字符。此处的'字符表示列表中的元素是字符串。 您的实际数据中没有任何这些。您只需要去除双引号。你不必担心单引号。你唯一的报价是"那些从文件中读取的。

另外，您可以简化

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

至

name = line.split(",")
