我们可以利用这个函数来统计文件的行数。 defcount_lines(filename):withopen(filename,'r')asfile:lines=sum(1for_infile)returnlines 1. 2. 3. 4. 在上述代码中,sum(1 for _ in file)使用了一个生成器表达式来生成一个包含文件行数的迭代器。sum()函数会将迭代器中的元素求和,从而得到文件的行数。
其中比较常用的库是line_count。首先我们需要安装这个库,可以使用pip命令进行安装: $ pip install line_count 1. 安装完成后,我们可以使用下面的代码来统计行数: importline_count file_path='example.py'line_count_result=line_count.count(file_path)print(f"The number of lines in the file is:{line_coun...
方法1:使用readlines()方法逐行读取文件内容,并利用len()函数统计行数。 def count_lines(filename): with open(filename, 'r') as file: lines = file.readlines() line_count = len(lines) return line_count filename = 'example.txt' line_count = count_lines(filename) print("文件", filename, ...

for line in open(thefilepath): count += 1 However, xreadlines does not return a sequence, and neither does a loop directly on the file object, so you can’t just use len in these cases to get the number of lines. Rather, you have to loop and count line by line, as shown in ...
