Assigning Values to Variables from List in Python 2.7


Assigning Values to Variables from List in Python 2.7

will be helpful for those in need If you're not dealing with large Excel worksheets, or any problematic data types (such as one described in the section Dates in Excel spreadsheets), you can simplify reading all rows into a single list, pop the header values for the insert columns, then call Cursor.executemany once to insert all values from the spreadsheet, passing a sequence of sequences for parameter values.
I've removed the numpy array population, since it's not necessary in the snippet provided.
code :
header_row = 0

# build list of lists that represents row values in worksheet,
# including column names from header row
rows = [worksheet.row_values(row) for row in range(worksheet.nrows)]

# extract list of column names to use for insert statement, values to be inserted remain
columns = rows.pop(header_row)

cnxn = pyodbc.connect(r"DRIVER={SQL Server};SERVER=XXXXXXXXXX\DEV_CON1;DATABASE=GGG;UID=AAA_dbo;PWD=XXXXXXXXX;")
cursor = cnxn.cursor()

# list of column names used to build SQL statement, including parameter placeholders (?)
populate_db = "insert into tblSnap_TEST ({}) values ({})".format(', '.join(columns),
                                                                 ', '.join('?' * len(columns)))

# insert is executed once for each sequence of parameter values
cursor.executemany(populate_db, rows)
cnxn.commit()
cnxn.close()

I hope this helps you . You don't need eval() or Function() for this. An array, as you suspected, will do the job nicely:
code :
(function() // keep outer scope clean
{
   // pages to load. Each name is used both for the request and the name
   // of the property to store the result in (so keep them valid identifiers
   // unless you want to use window['my funky page'] to retrieve them)
   var pages = ['viewer', 'artists', 'instores', 'specs', 'about'];

   for (var i=0; i<pages.length; ++i)
   {
      // "this" refers to the outer scope; likely the window object. 
      // And will result in page contents being stored in global variables 
      // with the same names as the pages being loaded. We use the with({})
      // construct to create a local scope for each callback with the
      // appropriate context and page name.
      with ({context: this, pageName: pages[i]})
         $.get("content.py?pageName=" + pageName, function(data)
            {context[pageName] = data;});
   }

})(); // close scope, execute anonymous function

// at this point, viewer, artists, etc. are populated with page contents 
// (assuming all requests completed successfully)

wish helps you Python variables are names for values. They don't really "contain" the values.
for var in var_list: causes 'var' to become a name for each element of the list, in turn. Inside the loop, var = num does not affect the list: instead, it causes var to cease to be a name for the list element, and instead start being a name for whatever num currently names.

This might help you Assigning values do not make sense on immutable types. I assume you would like to do this:
There is a list of int [1,2,3,4,5,6] and a list of int references which are initialized with default values [ref 0, ref 0, ref 0, ref 0, ref 0, ref 0]. You would like to update references to [ref 1, ref 2, ref 3, ref 4, ref 5, ref 6].
code :
fun assign([], []) = ()
  | assign(_, []) = raise error
  | assign(_, []) = raise error
  | assign(l::ls, r::rs)= (r := l ; assign(ls, rs))

Hope that helps This function takes, as an argument, a positive integer n and generates 3 random numbers between 200 and 625, the smallest random number will be called minValue, the middle random number will be called myTaret, and the largest random number will be called maxValue. , How about the following:
code :
>>> min, target, max = sorted([random.randrange(100, 625, 1) for i in range(3)])
>>> min, target, max
(155, 181, 239)
>>>

To fix this issue You don't need all the if and many variables, use dicts instead. You also don't need to use the done flag, zip will do it for you
code :
variables = {'cena': '', 'poznamkaCena': '', 'aktualizace': ''}
texts = {'Celková cena:': 'cena', 'Poznámka k ceně:': 'poznamkaCena', 'Aktualizace:': 'aktualizace'}

params = driver.find_elements_by_class_name('param-label')
values = driver.find_elements_by_class_name('param-value')

for param, value in zip(params, values):
    if param.text in texts:
        variables[texts[param.text]] = value.text
