if results:
for line in results:
print line[0] + ' - ' + line[1]
I need to insert a '-' between line[0] and line[1], but when I enter the above code, I get the error message 'coercing to Unicode: need string or buffer, int found'. Any suggestions on a way around this?
Thanks in advance.
the problem is that line[0] or line[1] holding an int number.
by using "+" and 'some string' you are telling python please append to the string the next string, but you have an int so the interpreter is raising a problem.
try to use:
if results:
for line in results:
print str(line[0]) + ' - ' + str(line[1])
"+" note in python will change it's "action" when meeting different data types. it's a very powerful feature but as default it cannot add different datatypes.

I need to find elements on a page by looking for text(), so I use xlsx as a database with all the texts that will be searched.
It turns out that it is showing the error reported in the title of the publication, this is my code:
search_num = str("'//a[contains(text()," + '"' + row[1] + '")' + "]'")
print(search_num)
xPathnum = self.chrome.find_element(By.XPATH, search_num)
print(xPathnum.get_attribute("id"))
print(search_num) returns = '//a[contains(text(),"0027341-66.2323.0124")]'
Does anyone know where I'm going wrong, despite having similar posts on the forum, none of them solved my problem. Grateful for the attention
Lot more quotes appear, Use python format() function to substitute the variable.
search_num ="//a[contains(text(),'{}')]".format(row[1])
Looks like you have extra quotes here
str("'//a[contains(text()," + '"' + row[1] + '")' + "]'")
Try changing to f"//a[contains(text(),'{row[1]}')]"
With this python's code I may read all tickers in the tickers.txt file:
fh = open("tickers.txt")
tickers_list = fh.read()
print(tickers_list)
The output that I obtain is this:
A2A.MI, AMP.MI, ATL.MI, AZM.MI, BGN.MI, BMED.MI, BAMI.MI,
Neverthless, I'd like to obtain as ouput a ticker string exactly formatted in this manner:
["A2A.MI", "AMP.MI", "ATL.MI", "AZM.MI", ...]
Any idea?
Thanks in advance.
If you want the output to look in that format you want, you would need to do the following:
tickers_list= "A2A.MI, AMP.MI, ATL.MI, AZM.MI, BGN.MI, BMED.MI, BAMI.MI"
print("["+"".join(['"' + s + '",' for s in tickers_list.split(",")])[:-1]+"]")
With the output:
["A2A.MI"," AMP.MI"," ATL.MI"," AZM.MI"," BGN.MI"," BMED.MI"," BAMI.MI"]
Code explanation:
['"' + s + '",' for s in tickers_list.split(",")]
Creates a list of strings that contain each individual value, with the brackets as well as the comma.
"".join(...)[:-1]
Joins the list of strings into one string, removing the last character which is the extra comma
"["+..+"]"
adds the closing brackets
Another alternative is to simple use:
print(tickers_list.split(","))
However, the output will be slightly different as in:
['A2A.MI', ' AMP.MI', ' ATL.MI', ' AZM.MI', ' BGN.MI', ' BMED.MI', ' BAMI.MI']
Having ' instead of "
A solution for that however is this:
z = str(tickers_list.split(","))
z = z.replace("'",'"')
print(z)
Having the correct output, by replacing that character
you can to use Split function:
tickers_list = fh.read().split(',')
I wrote code to append a json response into a list for some API work I am doing, but it stores the single quotes around the alphanumerical value I desire. I would like to get rid of the single quotes. Here is what I have so far:
i = 0
deviceID = []
while i < deviceCount:
deviceID.append(devicesRanOn['resources'][i])
deviceID[i] = re.sub('[\W_]', '', deviceID[i])
i += 1
if i >= deviceCount:
break
if (deviceCount == 1):
print ('Device ID: ', deviceID)
elif (deviceCount > 1):
print ('Device IDs: ', deviceID)
the desired input should look like this:
input Device IDs:
['14*************************00b29', '58*************************c3df4']
Output:
['14*************************00b29', '58*************************c3df4']
Desired Output:
[14*************************00b29, 58*************************c3df4]
As you can see, I am trying to use RegEx to filter non Alphanumeric and replace those with nothing. It is not giving me an error nor is it preforming the actions I am looking for. Does anyone have a recommendation on how to fix this?
Thank you,

You won't be able to use the default print. You'll need to use your own means of making a representation for the list. But this is easy with string formatting.
'[' + ', '.join(f'{id!s}' for id in ids) + ']'
The f'{id:!s} is an f-string which formats the variable id using it's __str__ method. If you're on a version pre-3.6 which doesn't use f-strings, you can also use
'%s' % id
'{!s}'.format(id)
PS:
You can simplify you're code significantly by using a list comprehension and custom formatting instead of regexes.
ids = [device for device in devicesRanOn['resources'][:deviceCount]]
if deviceCount == 1:
label = 'Device ID:'
elif deviceCount > 1:
label = 'Device IDs:'
print(label, '[' + ', '.join(f'{id!s}' for id in ids) + ']')
Is there a easy way to print the last string after you've split?
Input File:
Name:DOB:Age
Name:Name2:DOB:Age
I want the name and age...
So...
string = line.split(':')
print(string[0] + string[xxxx])
Is there anything that goes where xxxx is to always print the last string?
Thanks
string = line.split(':')
print(string[0] + string[-1])
I have an excel book with a couple of sheets. Each sheet has two columns with PersonID and LegacyID. We are basically trying to update some records in the database based on personid. This is relatively easy to do TSQL and I might even be able to get it done pretty quick in powershell but since I have been trying to learn Python, I thought I would try this in Python. I used xlrd module and I was able to print update statements. below is my code:
import xlrd
book = xlrd.open_workbook('D:\Scripts\UpdateID01.xls')
sheet = book.sheet_by_index(0)
myList = []
for i in range(sheet.nrows):
myList.append(sheet.row_values(i))
outFile = open('D:\Scripts\update.txt', 'wb')
for i in myList:
outFile.write("\nUPDATE PERSON SET LegacyID = " + "'" + str(i[1]) + "'" + " WHERE personid = " + "'" + str(i[0])
+ "'")
Two problems - when I read the output file, I see the LegacyID printed as float. How do I get rid of .0 at the end of each id? Second problem, python doesn't print each update statement in a new line in the output text file. How to I format it?
Edit: Please ignore the format issue. It did print in new lines when I opened the output file in Notepad++. The float issue still remains.
Can you turn the LegacyID into ints ?
i[1] = int(i[1])
outFile.write("\nUPDATE PERSON SET LegacyID = " + "'" + str(i[1]) + "'" + " WHERE personid = " + "'" + str(i[0])
+ "'")
try this..
# use 'a' if you want to append in your text file
outFile = open(r'D:\Scripts\update.txt', 'a')
for i in myList:
outFile.write("\nUPDATE PERSON SET LegacyID = '%s' WHERE personid = '%s'" %( int(i[1]), str(i[0])))
Since you are learning Python (which is very laudable!) you should start reading about string formatting in the Python docs. This is the best place to start whenever you have a question light this.
Hint: You may want to convert the float items to integers using int().
