在Python中从CSV文件读取行

您可以执行以下 *** 作：

with open("data1.txt") as f:    lis = [line.split() for line in f]        # create a list of lists    for i, x in enumerate(lis):   #print the list items         print "line{0} = {1}".format(i, x)# output line0 = ['Year:', 'Dec:', 'Jan:']line1 = ['1', '50', '60']line2 = ['2', '25', '50']line3 = ['3', '30', '30']line4 = ['4', '40', '20']line5 = ['5', '10', '10']

要么 ：

with open("data1.txt") as f:    for i, line in enumerate(f):          print "line {0} = {1}".format(i, line.split())# output         line 0 = ['Year:', 'Dec:', 'Jan:']line 1 = ['1', '50', '60']line 2 = ['2', '25', '50']line 3 = ['3', '30', '30']line 4 = ['4', '40', '20']line 5 = ['5', '10', '10']

编辑：

with open('data1.txt') as f:    print "{0}".format(f.readline().split())    for x in f:        x = x.split()        print "{0} = {1}".format(x[0],sum(map(int, x[1:])))# output          ['Year:', 'Dec:', 'Jan:']1 = 1102 = 753 = 604 = 605 = 20
