我正在尝试编写一个程序,如果可能的话,它需要一个三项式并对其进行因式分解。每当用户输入 A、B 和 C 时,三项式应该通过 Factor(product, summation) 函数获取,但我似乎无法弄清楚如何将 A 和 C 分配给乘积 arg,将 B 分配给我尝试在函数外部声明不同的变量,product = (a*c) 和 summation = b,但这没有意义,而且我总体上不知道如何将所有这些联系在一起。
import math
import cmath
def factor(product, summation):
for i in range(-abs(product), abs(product) + 1):
if i == 0:
continue
if product % i == 0: # Ensure i is a factor of the product
j = product // i # Find the corresponding factor
if i + j == summation: # Check if the sum of the factors matches the given summation
return i, j
return None
#Assign the coefficients
print('Follow this format: Ax^2 + Bx + C')
a = float(input('Enter A: '))
b = float(input('Enter B: '))
c = float(input('Enter C: '))
#Give a space between everything
print(' ')
print (f'{a}x^2 + {b}x + {c}')
factor(product, summation)
I tried declaring different variables outside the function, product = (a*c) and summation = b, but it doesn't make sense and I am overall lost on how to tie all of this together.
几乎已经掌握了!无需将多个变量传递给
factor
函数,只需在调用函数之前,在函数之外计算
product
和
summation
即可。
以下是的代码的修改方法:
import math
import cmath
def factor(product, summation):
for i in range(-abs(product), abs(product) + 1):
if i == 0:
continue
if product % i == 0:
j = product // i
if i + j == summation:
return i, j
return None
#Assign the coefficients
print('Follow this format: Ax^2 + Bx + C')
a = float(input('Enter A: '))
b = float(input('Enter B: '))
c = float(input('Enter C: '))
# Calculate product and summation here
product = a * c
summation = b
#Give a space between everything
print(' ')
print (f'{a}x^2 + {b}x + {c}')
# Now call the function with calculated values
factors = factor(product, summation)
if factors is not None:
print(f"The factors are: ({factors[0]}, {factors[1]})")
else:
print("No factors found.")
说明:
-
计算
product
和summation
: 在获取a
、b
和c
的值之后,我们直接计算product = a * c
和summation = b
。 -
将计算值传递给函数:
我们现在使用计算的值调用
factor(product, summation)
,将product
和summation
作为参数传递。 -
处理结果:
factor
函数返回一个包含两个因子的元组,或者如果找不到因子,则返回None
。我们检查返回值并相应地打印结果。
通过这种方式,无需将多个值塞入单个参数,而可以在调用函数之前执行必要的计算,从而使代码更清晰、更有条理。
