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)

在从文件中读取数据的同时，它还在名称中添加“and”。 如果名称为COLIN，则会在列表名称中保存为“COLIN”。 我该怎么修？ 输入文件

输出 ['“玛丽”'，'“…”，'“…”，'“…”，…]

Answer 1

如果要从字符串中删除这些字符，可以执行以下操作：

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

这将用空字符串替换"的所有实例

如果您只想在字符串的末端删除它们，可以这样做

s = s.strip("\"")

如果要确保每端只删除一个引号，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包含引号，则可以将其简化为：

s = s[1:-1]

然而，这个文件看起来是一个csv文件，使用csv库解析这些文件要好得多

Answer 2

这是我的解决办法。它支持以逗号分隔的行中的多个名称，也支持文件中的多行

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 3

您可以通过以下方式从Python中的字符串中删除第一个和最后一个字符：

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

这将打印 COLIN 而不是 'COLIN'
