我想从我的python脚本中获取excelsheet中的特定单元格值.我碰到xlrd,xlwt,xlutils读模块/从excelsheet写入/.
我用hi,hello创建了myfile.xls,如何在第一列的3个单元格中创建.
示例代码: -
import xlrd
workbook = xlrd.open_workbook('myfile.xls')
worksheet = workbook.sheet_by_name('Sheet1')
num_rows = worksheet.nrows - 1
curr_row = -1
while curr_row < num_rows:
curr_row += 1
row = worksheet.row(curr_row)
print row
输出: -
[text:u'hi']
[text:u'hello']
[text:u'how']
我想从excelsheet读取特定的单元格值,有人可以建议我,如果有办法做到这一点？
我需要在yaml文件中使用环境变量“ PATH”，该环境变量需要使用脚本进行解析。
这是我在终端上设置的环境变量：
$ echo $PATH
/Users/abc/Downloads/tbwork
这是我的sample.yml：
---
Top: ${PATH}/my.txt
Vars:
- a
- b
当我用脚本解析该Yaml文件时，看不到PATH变量的实际值。
这是我的脚本：
import yaml
import os
import sys
stream = open("sample.yml", "r")
docs = yaml.load_all(stream)
for doc in docs:
for k,v in doc.items():
print k, "->", v
print "\n",
输出：
Top -> ${PATH}/my.txt
Vars -> ['a', 'b']
预期输出为：
Top -> /Users/abc/Downloads/tbwork/my.txt
Vars -> ['a', 'b']
如果我做错了事，有人可以帮我弄清楚做事的正确方法吗？
如何检查列表中是否只有两个可以重复的特定元素？
例如：我希望出现在列表中的有效元素只有2个：
1. abstract.f
2. None
如果list包含任何其他元素，则应抛出错误消息。
list1 = ['abstract.f', None, None, 'abstract.f']
# This is a valid list as it doesn't have any other element than 2 of above.
list1 = ['abstract.f', None, 'xyz']
# This is invalid list as it has 'xyz' which is not expected.
我需要解析这个输出: -
S1-link-id eNB-IP-Address MME-IP-Address Facing State ------------------------------------------------------------------- 303 141.1.1.2 191.1.1.2 eNodeB Established 301 141.1.1.2 191.1.1.2 MME Established 306 141.1.1.3 191.1.1.2 eNodeB Established 304 141.1.1.3 191.1.1.2 MME Established 309 141.1.1.4 191.1.1.2 eNodeB Established 307 141.1.1.4 191.1.1.2 MME Established
我想为单个id(第一列)获取多个值.对于"303" - 我需要enb,mme ip地址,面向和状态值,对于其他ID也是如此.
一个所需输出的正则表达式: -
\s*(?P<id>\d+)\s+(?P<enb_adr>\d+\.\d+\.\d+\.\d+)\s+(?P<mme_adr>\d+\.\d+\.\d+\.\d+)\s+(?P<facing>\w+)\s+(?P<state>\w+)\s*
在此之后坚持如何继续以获得整个输出的期望值.
I have a list in Perl.
@alist=("a_vld","a_sf","a_ef","a_val");
print join(',', @alist), "\n";
Output:
a_vld,a_sf,a_ef,a_val
How can I re-order the elements in list such that its output is as following expected output:
a_sf,a_ef,a_vld,a_val
Note: a_ will keep changing with different strings but I want to preserve the order of sf,ef,vld,val
