# 打开文件withopen('file.txt','r')asfile:line_count=0for_infile:line_count+=1# 输出文件的行数print(f'文件的行数为:{line_count}') 1. 2. 3. 4. 5. 6. 7. 8. 方法三:使用enumerate()方法 使用enumerate()方法可以同时获取行号和行内容,通过遍历文件对象并计数,可以得到文件的行数。 # 打...
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, ...
detailCountInfo.append([os.path.basename(filePath), lineCountInfo])else: detailCountInfo.append([filePath, lineCountInfo]) CountFileLines()函数根据后缀判断文件类型并调用相应的统计函数,并扩展isBlockComment列表以存储两种Python块注释(三单引号和三双引号)。除此之外,别无其他修改。 三. 效果验证 将本文...

要统计并输出文件的行数和列数,可以使用以下代码: def count_lines_columns(filename): with open(filename, 'r') as file: lines = file.readlines() line_count = len(lines) column_count = len(lines[0].split()) print("行数:", line_count) print("列数:", column_count) count_lines_...

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 ...
