xlwt无法解析公式中的IF语句

Question

i'm trying to write a formula to a series of cells by building the string. for instance i want to display the word "true" in a cell if the corresponding cell in column G contains the word "monkey" in it.

for rowi in range(totalRows):
    thisRow = str(rowi)
    functionString = r'IF(ISNUMBER(SEARCH("monkey",G'+thisRow+')),("true")

this will produce the string "IF(ISNUMBER(SEARCH("monkey",G1)),("true")" -- if i then pass that to xlwt.Formula...

    ws.write(rowi+1, 0, xlwt.Formula(functionString))

i get this error...

File "C:\Python27\Lib\site-packages\xlwt\ExcelFormula.py", line 22, in __init__
    raise ExcelFormulaParser.FormulaParseException, "can't parse formula " + s
xlwt.ExcelFormulaParser.FormulaParseException: can't parse formula IF(ISNUMBER(SEARCH("bitmap",G2)),("true")

is it possible to use this type of function with xlwt?

Answer 1

Ignoring the impossibility that you typed in monkey and G1 whereas the error message mentions bitmap and G2 ...

I suggest that you fire up Excel, select a cell, type = and paste your formula ... what happens? This check is always advisable before going public, and is available even if your internet connection is broken.

Notes:

(1) the parentheses around "true" are redundant

(2) simpler: ISNUMBER(SEARCH("bitmap",G2))

(3) Are you really expecting that a user will open the resulting XLS file and type text into column G?
