使用awk/sed脚本提取函数参数

Question

我有Python代码，我想从中提取HTTP参数。在

在下面的内容中：我怎样才能使def行保持独立，但是从剩余的行中只保留params['...']内的内容，也许在一行上有多个params['...']：

输入：

def delete_bazooka (request):
    BType.objects.get(id=params['id']).delete()
    BType.objects.get(name=params['name']).delete()
def create_bazooka (request):
  s = Skill.objects.get(id=params['skill'])
  l = Level.objects.get(id=params['level'])
  bt = BType.objects.get(name=params['type'])
  b = Bazooka(type=qt, bin=b, bin_sequence=b.count, text=params['text'], explanation=params['chocolate'], passage=p)
def delete_hoop (request):
  h = Hoop.objects.get(id=params['id'])

期望输出：

^{pr2}$

Answer 1

{1`exp>只能使用匹配的标志

grep -Eo "(?def .*|'[a-z]+')" test.txt

Answer 2

使用awk

awk -F\' '{$0=/^def/?$0:$2" "$4}1' test.txt
