Question

我想将输出的print语句重定向到文本文件。我已经导入了sys并在下面尝试过。

import pprint
import os
import math
import sys

class ExportLimits(object):
    MMAP_ITER_TRIPS = 'manpower_mappings.map_iterator_trips'

def __init__(self, workset, crew_type, bid_period, divisor_files=None):
    log_file = "/opt/test/test_user/data/ESR_DATA/etab/slogfile.txt"
    sys.stdout = open(log_file, 'w')
    self.workset = workset
    self.crew_type = crew_type
    self.bid_period = bid_period
    self.tm = workset.getTM()
    self.crew_bid_period = self.crew_type + "+" + self.bid_period
    self.bid_period = self.tm.table('qf_user_bid_period')[(self.crew_bid_period)]
    self.period = Period(self.bid_period.bpstart, self.bid_period.bpend)
    self.filter_matcher = self._get_filter_matcher()
    self.iterator_trips = rave_api.eval(\
            ExportLimits.MMAP_ITER_TRIPS)[0]
    self.divisor_reader_lh = divisor_reader_lh.DivisorReader(\
            divisor_files=divisor_files)
    self.divisor_reader_sh = divisor_reader_sh.DivisorReader(\
            divisor_files=divisor_files)
    self.pp_start = self.period.getStart()
    self.pp_end = self.period.getEnd()

def export_limits(self, item_type):
    if item_type == 'DKSH':
       self._mandays_limits(SLKHH_GROUPS)
    else:
       self._mandays_limits(LAJSDLH_GROUPS)
def _mandays_limits(self, groups):
  crews = [self.tm.table('crew')[('99172447',)],
             self.tm.table('crew')[('7654678',)]]
  generator = ((crew, self.filter_matcher.getFilterNamePeriodsMap(crew.id))
                 for crew in self.tm.table('crew'))

  minres = defaultdict(lambda :RelTime(0))
  maxres = defaultdict(lambda :RelTime(0))

  for crew, group_to_periods in generator:
      print crew, group_to_periods
      try:
         crew_filter, period = group_to_periods.iteritems().next()
      except StopIteration:
         continue
      if crew_filter not in groups:
         continue

它部分适用于我。我可以打印几行，但不完全。请找到我的日志文件的以下输出，其中只打印了较少的行而不是完整的日志。由于某种原因，它没有完全打印。（请查看日志文件的最后一行，其中只打印“alia”。）

日志文件：

crew _id =“133245”id =“176543”empno =“8761890”sex =“M”   birthday =“19681217”name =“MICHEAL”forenames =“LUCAS”maincat =“C”   preferredname =“ESWAR”initials =“LL”joindate =“20010910 00:00”   comjoindate =“20010910 00:00”   _void =“title，logname，si，bcity，bstate，bcountry，alias，comenddate”{'X-SYD-BB-AUSLLH'：[26JUN2017 00：00-21AUG2017 00:00]}

crew _id =“214141”id =“132451”empno =“145432”sex =“M”   birthday =“19630904”name =“ESWARF”forenames =“FJDJSK”maincat =“C”   preferredname =“ESWADF”initials =“WL”joindate =“20010910 00:00”   comjoindate =“20010910 00:00”   _void =“称号，日志名，SI，bcity，bstate，bcountry，其他外

请检查并提出建议。

您可以这样编写：

，而不是使用sys.stdout

output_file = open(log_file, 'w')

output_file.write('testing asdasdfsd')

或者如果你想在日志文件中写下各种打印值，那么：

output_file = open（log_file，'w'）

sys.stdout = output_file

就是这样。

将stdout重定向到Python中的文本文件？
