检查文件中的行是否包含Python中的大写字母

Question

我正在逐行读取一个文件,让我说我不关心任何事情,除了"如果"该文件的这一行包含一个大写字母.因为如果它,我想使用它.如果没有,我不想使用文件的这一行.

我可以只使用一个if语句吗？或者我必须使用for循环.我已经有两个嵌套语句.

我的代码:

with open(var) as config_file: #open file
for line in config_file: #line by line reading of file
    #if "description" and capital letter is contain in line:
        line = line.replace('\n' , '').replace('"' , '').replace(']' , '') #removes all extra characters
        i = "| except " + (line.split("description ", 1)[1]) + " " #split the line and save last index (cust name)
        cus_str+=i #append to string
config_file.close()

是.内置any函数使这很简单:

with open(filename) as f:
    for line in f:
        if any(letter.isupper() for letter in line):
            print(line)
