你好新的編碼,並具有與蟒蛇IM一些問題得到這個錯誤爲+不支持的操作類型:「浮動」和「STR」
C:\Users\\Desktop\exam review\review 1.py", line 89, in main
endBalance = begBalance - totalWithdrawals + totalDeposits
TypeError: unsupported operand type(s) for +: 'float' and 'str'
下面的代碼:
def main():
#Declare and initialize variables
#float = 0.0, with1 =0.0, with2 = 0.0, with3 = 0.0
with1 = with2 = with3 = 0.0
#float deposit1 = 0.0, deposit2 = 0.0, deposit3 = 0.0
deposit1 = deposit2 = deposit3 = 0.0
#float totalWithdrawals = 0.0, totalDeposits = 0.0, endBalance = 0.0, begBalance = 0.0
totalWithdrawals = totalDeposits = endBalance = begBalance = 0.0
#string acctNumber = 「 「
acctNumber = ""
#string firstName = 「 」, lastName = 「 」
firstName = lastName = ""
#int age = 0
age = 0
#string userName =」 「, convertedAcctNumber = 「 「
userName = convertedAcctNumber = ""
#Intro
print("This program will show your bank statement\n")
#Open file 「January.txt」 for input
infile = open("January.txt", "r")
#Read in line1 and store in acctNumber
line1 = infile.readline()
acctNumber = line1
#Read in line2 and store in begBalance
line2 = infile.readline()
begBalance = line2
#Convert begBalance to float
begBalance = float(begBalance)
#Read in line3 and split into with1, with2, with3
line3 = infile.readline()
with1, with2, with3 = line3.split(",")
#Convert with1, with2, and with3 to float
with1 = float(with1)
with2 = float(with2)
with3 = float(with3)
#Read in line4 and split into deposit1, deposit2, deposit3
line4 = infile.readline()
deposit1, deposit2, deposit3 = line4.split(",")
#Convert deposit1, deposit2 and deposit3 into float
depoit1 = float(deposit1)
depoit2 = float(deposit2)
depoit3 = float(deposit3)
#Close file
infile.close()
#Prompt for firstName
firstName = input("What is your first name: ")
#Prompt for lastName
lastName = input("What is your last name: ")
#Prompt for age
age = eval(input("What is your age: "))
#Use string manipulation to create username
userName = (firstName[0] + lastName[:5] + str(age)).lower()
#Use string manipulation to create convertedAcctNumber
convertedAcctNumber = acctNumber[0:3] + "-" + acctNumber[3:5] + "-" + acctNumber[5:]
#Calculate totalDeposits
totalDeposits = deposit1 + deposit2 + deposit3
#Calculate totalWithdrawals
totalWithdrawals = with1 + with2 + with3
#Calculate endBalance
endBalance = begBalance - totalWithdrawals + totalDeposits
#Display report on screen
print("Broward College National Bank".center())
print("Name \t\t\t UserName\t\t\t Account Number")
print("-----------------------------")
#Open 「January statement.txt」 for output
#Write the report to the file
#Close file `
因此,我有非常有限的編程知識,我嘗試了以下內容,使所有內容都變爲浮動狀態(我已經將deposit1 deposit2 deposit3和with1 with2 with3移入浮動塊,所以當它們添加時,totalDeposits和totalWithdrawls自己變成浮動塊,使以下多餘?)
'#Calculate totalDeposits
totalDeposits = deposit1 + deposit2 + deposit3
totalDeposits = float(totalDeposits)
#Calculate totalWithdrawals
totalWithdrawals = with1 + with2 + with3
totalWithdrawals = float(totalWithdrawals)
#Calculate endBalance
endBalance = begBalance - totalWithdrawals + totalDeposits
endBalance = float(endBalance) '
然後我得到這個錯誤
Traceback (most recent call last):
File "<pyshell#28>", line 1, in <module>
main()
File "C:\Users\\Desktop\exam review\review 1.py", line 82, in main
totalDeposits = float(totalDeposits)
ValueError: could not convert string to float: '200.56234.56352.35\n'
這些都是閱讀下載4號線的值.. SOOO即時通訊幾乎被卡住,不知道自己能做什麼,謝謝大家的幫助。
與同爲'depoit2'和'depoit3 '當然。 – abarnert
哈哈得倍加關注,謝謝你的幫忙! – user3320792
