[英]Python - Write Header Once - Loop isn't working properly
I am trying to write an "order file" with a Header and Detail Lines. 我正在尝试用标题和细节线写一个“订单文件”。 I am successfully getting the order Header to write to file, but only one detail line seems to get written to the file.
我成功获取了要写入文件的订单标题,但只有一个详细信息行似乎写入文件。
for k, v in atlantic_billing.iteritems():
XHORNO = str(digits + counter)
XHCSNO = k
print XHCSNO
machines = v
line = 1
counter = counter + 1
header_written = False
try :
for machine in machines :
XDORNO = XHORNO
XDORSQ = line
line = line + 1
XDITD1 = ranpak_dict[machine]['MODEL']
XDITD2 = ranpak_dict[machine]['SN']
XDCAVC = ranpak_dict[machine]['TOTAL']
print XDORSQ, XDITD1, XDITD2, XDCAVC
if XDCAVC > 0 :
if header_written == False :
with open(XHORNO + ".txt", 'w') as order:
order.write("H01, " + XHORNO + ", " + XHCSNO + "\n")
order.write("D01," + str(XDORSQ) + ", " + ' EQPRANUSER, ' + XDITD1 + ", " + XDITD2 + ", " + XDCAVC + "\n")
else :
order.write("D01," + str(XDORSQ) + ", " + ' EQPRANUSER, ' + XDITD1 + ", " + XDITD2 + ", " + XDCAVC + "\n")
success.append(machine)
header_written = True
except KeyError, e:
issues.append(machine)
When opening the file, you should use the mode "A"
else the file will be overwritten at each loop (again and again): 打开文件时,应使用
"A"
模式,否则文件将在每个循环中被覆盖(一次又一次):
with open(XHORNO + ".txt", 'a') as order:
...
see https://docs.python.org/3/library/functions.html#open 请参阅https://docs.python.org/3/library/functions.html#open
An other option is to take the with
block over the for block. 另一种选择是在for块上
with
块。
You need to open the file only once and not inside the loop 您只需要打开一次文件而不是循环内部
for k, v in atlantic_billing.iteritems():
XHORNO = str(digits + counter)
with open(XHORNO + ".txt", 'w') as order: # <--- here you go
XHCSNO = k
print XHCSNO
machines = v
line = 1
counter = counter + 1
header_written = False
try :
for machine in machines :
XDORNO = XHORNO
XDORSQ = line
line = line + 1
XDITD1 = ranpak_dict[machine]['MODEL']
XDITD2 = ranpak_dict[machine]['SN']
XDCAVC = ranpak_dict[machine]['TOTAL']
print XDORSQ, XDITD1, XDITD2, XDCAVC
if XDCAVC > 0 :
if header_written == False :

Try this: 尝试这个:
for k, v in atlantic_billing.iteritems():
XHORNO = str(digits + counter)
XHCSNO = k
print XHCSNO
machines = v
line = 1
counter = counter + 1
header_written = False

for machine in machines :
XDORNO = XHORNO
XDORSQ = line
line = line + 1

XDITD2 = ranpak_dict[machine]['SN']
XDCAVC = ranpak_dict[machine]['TOTAL']
print XDORSQ, XDITD1, XDITD2, XDCAVC
if XDCAVC > 0 :
with open(XHORNO + ".txt", 'a') as order:
if header_written == False :
order.write("H01, " + XHORNO + ", " + XHCSNO + "\n")
order.write("D01," + str(XDORSQ) + ", " + ' EQPRANUSER, ' + XDITD1 + ", " + XDITD2 + ", " + XDCAVC + "\n")
header_written = True
