在python中组合2个列表

# combine the lists
zipped = zip(alist, blist)

# write to a file (in append mode)
file = open("filename", 'a') 
for item in zipped:
    file.write("%d, %d\n" % item) 
file.close()

文件中的结果输出将是:

 1,2
 2,3
 3,4
 5,5

为了完整起见,我将补充 Ben's solution 那个 itertools.izip 如果迭代使用结果,尤其是对于更大的列表更可取,因为最终结果不是实际的列表而是生成器:

from itertools import izip
zipped = izip(alist, blist)
with open("output.txt", "wt") as f:
    for item in zipped:
        f.write("{0},{1}\n".format(*item))

文件 izip 可以找到 here .
