创建和写入文件-Python

Question

I want to create a file with a name according to a variable. That is my first problem and then I want to write what is printed to the screen in console to that file.

This is what I have, I am currently getting an error at the .open. - 'EOL while scanning string literal'. However I guess there will be more errors to follow that.

saveFile.open((fileName)".txt,'w')
saveFile.write("Final Quote Price: £", format(FinalPrice, '.2f'), "Plus VAT")
saveFile.close()

I just put an example in the .write part but I want it to write certain parts of what is printed to the screen in console to file - is that possible?

Answer 1

i think u missed a + between your variable and string literal. saveFile.open((fileName)+".txt,'w')

Answer 2

There are missing quotes:

saveFile = open(fileName+".txt",'w')
saveFile.write("Final Quote Price: £{:.2f} Plus VAT".format(FinalPrice))
saveFile.close()

Answer 3

saveFile.open(fileName + ".txt",'w')
saveFile.write("Final Quote Price: £" + format(FinalPrice, '.2f') + "Plus VAT")
saveFile.close()

This should work

Answer 4

There is a double quota lost in your code, try this,

saveFile.open((fileName)+".txt",'w')
saveFile.write("Final Quote Price: £", format(FinalPrice, '.2f'), "Plus VAT")
saveFile.close()

Answer 5

To write and to read date from a file with a variable name:

fileName = 'fileData'
finalPrice = 12.003321

fileObj = open(fileName + ".txt", 'w')
fileObj.write("Final Quote Price: £" + format(finalPrice, '.2f') + "Plus VAT")
fileObj.close()

with open(fileName + '.txt', 'r') as file:
    fileString = file.read()
    print("Line: " + fileString)
