我对我的项目的print（tmp [3]）函数感到困惑。当打印项目tmp [3]时，它给了我两行，其中第一行带有值，另一行为空。一切顺利进行到第132行。
该程序的目标是打印一个。工资单摘要报告基于先前程序的信息（具有不同的费率）。您应该使用单个功能来执行以下操作：
[计算正常工作时间（40小时及以下）计算加班时间（超过40小时的加班时间）计算常规工资（常规时间乘以常规工资）计算加班工资（加班时间乘以正常工资乘以1.5）计算总工资计算预扣的联邦税额（占总工资的15.1％）计算预扣的州税金额（占总工资的5.5％）计算被扣留的医疗保险金额（占总工资的1.2％）计算扣留的社会保障金额（占总工资的4.8％）计算扣除总额（联邦税+国家税+医疗保险+社会保障）计算净工资（总工资-扣除额）计算净额（每个人的总计）打印（到屏幕上）干净的摘要报告（请参见上面的输出）打印（在屏幕上）总净工资。
我找到了基于输入的版本的功能，因此，从csv中提取数据并在功能中使用它对我来说是一个挑战。
如果您想要更简单的复制和以前类似的程序，这里是链接：Read records from CSV file and print report
print（tmp [3]）的预期结果是“ 10”。实际结果。“ 10”。我不知道为什么它会额外打印一行。我认为这个问题的症状是无法计算正常工资= Payrate * hoursWorked。预期输出为420。42（支付率）* 10（小时）= 420这是第133行的错误“ TypeError：无法将序列乘以'float'类型的非整数”这是一项家庭作业，我只是想解决这个错误，因此放置我的整个程序似乎是不必要的。
这里是csv文件：
First, Last, Hours, Pay
Matthew, Hightower, 42, 10
Samuel, Jackson, 53, 12.58
Catherine, Jones, 35, 19.43
这是整个程序。def main（）：
results = get_data("employeestest.csv")
payrollSummaryReport(results)
def get_data(fname):
Function returns the dictionary with following
format:
{ 0 : {
"fname": "...",
"lname": "...",
"gross": "...",
},
1 : {
....,
,,,,
},
}
结果= {}＃返回值i = 0＃如果您想压缩range（）用open（fname，'r'）as f：
for line in f.readlines()[1:]:
result[i] = {}
tmp = line.split(",") # list of values from file
# access file values by their index, e.g.
# tmp[0] -> first name
# tmp[1] -> last name
# tmp[2] -> hours
# tmp[3] -> pay rate
employeeRegularHours, employeeOvertimeHours = calculateRegularHours(tmp[2])
employeeOvertimeHours = calculateOvertimeHours(tmp[2])
employeeTotalHours = calculateTotalHours(employeeRegularHours, employeeOvertimeHours)
print(tmp[3])
This is were I print the item but it comes out to
"10
"
I don't know why it skips a line. I found this error through this "TypeError:can't multiply sequence by non-int of type 'float'" at line 132

f.readlines的输出包括行尾（EOL）字符，因此，如果在逗号上分割行并打印最后一个项目，它将在行尾字符上打印值and。如果您执行print(repr(tmp[3]))，将会看到类似'10\n'的内容。
您可以像这样从行中删除EOL：
tmp = line.strip().split(",")
但是，由于您正在处理csv文件，因此可以使用Python的内置csv模块，该模块将为您处理一些详细信息
import csv
# Do stuff
with open(fname, 'r', newline='') as f:
reader = csv.reader(f)
# Skip header row
next(reader)
# reader yield lists, but since we know each list will have
# the same number of elements we can unpack them into
# four separate variables - this is more readable than
# referencing by index.
for first_name, last_name, hours, pay_rate in reader:
employeeRegularHours, employeeOvertimeHours = calculateRegularHours(hours)
employeeOvertimeHours = calculateOvertimeHours(hours)
employeeTotalHours = calculateTotalHours(employeeRegularHours, employeeOvertimeHours)
# Do more stuff
请注意，从文件中读取时hours和pay_rate是字符串。如果要将它们用作数字，则需要根据所需的数字类型使用int或float进行转换。
