python - 如何只输出列表数据中的字符串？

Question

我的文件读取 teamNames.txt 文件，该文件是:

Collingwood

Essendon

Hawthorn

Richmond

代码:

file2 = input("Enter the team-names file: ") ## E.g. teamNames.txt

bob = open(file2)
teamname = []

for line1 in bob: ##loop statement until no more line in file
    teamname.append(line1)

print(teamname)

输出为:

['Collingwood\n', 'Essendon\n', 'Hawthorn\n', 'Richmond\n']

我想让它的输出如下:

Collingwood, Essendon, Hawthorn, Richmond

Answer 1

一种选择是使用 replace() 函数。我已修改您的代码以包含此功能。

file2= input("Enter the team-names file: ") ## E.g. teamNames.txt

bob =open(file2)
teamname = []

for line1 in bob: ##loop statement until no more line in file
    teamname.append(line1.replace("\n",""))

print(teamname)

会给你输出:

['Collingwood', 'Essendon', 'Hawthorn', 'Richmond']

然后您可以修改teamname以获得您请求的输出:

print(", ".join(teamname))
