我有这个错误：缩进错误：在第 19 行的"if"语句之后需要一个缩进块！我搞错了吗？

Question

# Variables to represent the base hours and
# the overtime multiplier.
base_hours = 40
# Base hours per week
ot_multiplier = 1.5 # Overtime multiplier
# Get the hours worked and the hourly pay rate.
hours = float(input('Enter the number of hours worked: '))
pay_rate = float(input('Enter the hourly pay rate: '))
# Calculate and display the gross pay.
if hours > base_hours:
# Calculate the gross pay with overtime.
# First, get the number of overtime hours worked.
overtime_hours = hours - base_hours
# Calculate the amount of overtime pay.
overtime_pay = overtime_hours * pay_rate * ot_multiplier
# Calculate the gross pay.
gross_pay = base_hours * pay_rate + overtime_pay
else:
# Calculate the gross pay without overtime.
gross_pay = hours * pay_rate
# Display the gross pay.
print(f'The gross pay is ${gross_pay:,.2f}.')

Answer 1

在Python中，if和else语句语句中的所有内容都必须缩进。根据PEP 8，缩进应为4个空格。

所以，你的代码应该是这样的：

if hours > base_hours:
# Calculate the gross pay with overtime.
# First, get the number of overtime hours worked.
overtime_hours = hours - base_hours
# Calculate the amount of overtime pay.
overtime_pay = overtime_hours * pay_rate * ot_multiplier
# Calculate the gross pay.
gross_pay = base_hours * pay_rate + overtime_pay
else:
# Calculate the gross pay without overtime.
gross_pay = hours * pay_rate
# Display the gross pay.
print(f'The gross pay is ${gross_pay:,.2f}.')
