text_file = open("Output.txt", "w")
text_file.write("Purchase Amount: %s" % TotalAmount)
text_file.close()
with open("Output.txt", "w") as text_file:
text_file.write("Purchase Amount: %s" % TotalAmount)
如果你使用的是Python2.6或更高版本，则最好使用 str.format()
with open("Output.txt", "w") as text_file:
text_file.write("Purchase Amount: {0}".format(TotalAmount))
对于python2.7及更高版本，你可以使用{}代替{0}
with open("Output.txt", "w") as text_file:
print("Purchase Amount: {}".format(TotalAmount), file=text_file)
python3.6引入了f字符串作为另一种选择
with open("Output.txt", "w") as text_file:
print(f"Purchase Amount: {TotalAmount}", file=text_file)
