python学习之——计算给出代码中注释、代码、空行的行数

题目：计算给出代码中注释、代码、空行的行数

来源：网络

思路：注释行以 ‘#’开头，空行以 ‘\n’ 开头，以此作为判断

def count_linenum(fname): fobj = open(fname,"rU") #print fobj.readlines() count_blankline = 0 count_notes = 0 count_code = 0 for eachLine in fobj: if eachLine[0] == '\n': count_blankline += 1 elif eachLine[0] == '#': count_notes += 1 else: count_code += 1 print "count_blankline:%d" %count_blankline print "count_notes:%d" %count_notes print "count_code:%d" %count_notes fobj.close() if __name__ == '__main__': filename = raw_input("please enter filename:") count_linenum(filename)
