如何從數組中打印字符串列表

Question

我需要一些幫助與我的代碼，我存儲數組中的字符串列表，當我嘗試打印字符串列表，它不會讓我打印它們當我在循環中使用變量時。

pos_start = list() 
pos_top = list() 
pos_width = list() 
pos_height = list() 
prog_title = list() 

for ind, row in enumerate(programs): 
    programs_top = 315 
    program_height = 33 
    program_gap = 3 
    position_start = start_pos 
    position_top = programs_top + channel_index * (program_height + program_gap + 1.5) 

    #create width size for per program button 
    if program_length >= 10 and program_length <= 45: #30 mins 
     program_width = 342 

    pos_start.append(position_start) 
    pos_top.append(position_top) 
    pos_width.append(program_width) 
    pos_height.append(program_height) 
position_start = map(str, pos_start) 
position_top = map(str, pos_top) 
program_width = map(str, pos_width) 
program_height = map(str, pos_height) 
program_title = map(str, prog_title) 

for position_start, position_width, position_height, program_title in zip(pos_start, pos_width, pos_height, prog_title): 
    print position_start 

這裏是position_start輸出：

13:41:23 T:4812 NOTICE: ['375', '1073', '1771', '2120', '2469', '2818', '3167', '3516',

'23060', '23409', '23758', '24107', '24456', '24805', '25154', '25503', '25852', '26201', '26550', 
'26899', '27248', '27597', '28295', '28993'] 

我可以能夠使用print position_start外的for循環。

你能告訴我如何打印每個字符串，我想從數組中讀取字符串嗎？

我嘗試使用for position_start, position_width, position_height, program_title in zip(pos_start, pos_width, pos_height, prog_title):打印每個字符串，但它不會讓我。

任何想法？

Answer 1

for item in position_start: 
    print item 

如果他們都是相同的長度（我不推薦並行陣列，因爲它很容易讓他們成爲一個項目關閉），你可以這樣做：

for i in range(0, len(position_start)): 
    print position_start[i] 
    print position_top[i] 
    print program_width[i] 
    print program_heigh[i] 
    print program_title[i] 

你也可以壓縮它們，就像您試圖獲取元組列表一樣。這將適用於甚至不均勻的列表。以下是一個示例：

import itertools 
l1 = [1, 2, 3] 
l2 = [4, 5, 6, 7] 
listZipped = itertools.izip_longest(l1, l2) 

for item in listZipped: 
    print item
