用递增的数字替换字符

Question

text = "Subjects cover: Warehouse Operations;  effective communication,Speed Functions; Newton laws of motion,Fiber Communication; sea level transmission"

如何使用“；”替换先前的“；”替换找到的数字“；”替换找到的“：”，这是我要查找的输出

output="Subjects cover: 1)Warehouse Operations: effective communication 2)Speed Functions: Newton laws of motion 3) Fiber Communication: sea level transmission"

也就是说，它会在哪里找到“；“它会找到上一个”，“并用一个“数字”替换它”，然后用“；”替换后面的“；”和“：”

我一直试图用regex来做，但是代码变得非常糟糕&；非音速的

Answer 1

以下是一种方法：

text = "Subjects cover: Warehouse Operations;  effective communication,Speed Functions; Newton laws of motion,Fiber Communication; sea level transmission"

# split the string
t1 = text.split(':')

# modify the strings
rf = [[y.replace(';', ':').strip() for y in x.split(',')] for i, x in enumerate(t1[1:])][0]

# join the results
result = t1[0] + ' ' +  ' '.join([f'{i}) {x}' for i,x in enumerate(rf, 1)])

print(result)

'Subjects cover 1) Warehouse Operations:  effective communication 2) Speed Functions: Newton laws of motion 3) Fiber Communication: sea level transmission'
