You can capture the output of the print function by redirecting it to a variable using the "redirect_stdout" method from the "contextlib" module. Here's an example:
```
from contextlib import redirect_stdout
from io import StringIO
# create a StringIO object to capture the output
output = StringIO()
# redirect the output of the print function to the StringIO object
with redirect_stdout(output):
print("Hello, world!")
# get the captured output as a string
output_str = output.getvalue()
# print the captured output
print(output_str)
```
This will output:
```
Hello, world!
```

ZooKeeper getData failed after 1 attempts
这个问题可能是指ZooKeeper客户端在尝试获取节点数据时失败了,尝试了1次但是失败了。这可能是由于ZooKeeper服务器不可用或网络连接问题引起的。如果您遇到这个问题,建议您检查ZooKeeper服务器是否可用,并确保您的网络连接正常。您还可以尝试增加重试次数,以提高获取数据的成功率。如果问题仍然存在,请检查ZooKeeper客户端的日志,以便更好地了解问题的原因。
can you show me the concrete code after modification?
Sure, here is the modified code with the fixes applied:
```
module inner_submod (input logic [9:-1][2:0] sub_input, output logic [9:-1][2:0] sub_output);
assign sub_output = sub_input + 1;
endmodule
module test_top;
typedef struct packed {
logic [9:-1][2:0] a;
} ST1;
typedef packed struct {
ST1 st1;
ST1 st2[2:0];
} ST2;
inner_submod submod1 (
.sub_input(st2.st2[0].a),
.sub_output(st2.st2[0].a)
);
inner_submod submod2 (
.sub_input(st2.st2[0].a),
.sub_output(st2.st2[0].a)
);
inner_submod submod3 (
.sub_input(st2.st2[1].a),
.sub_output(st2.st2[1].a)
);
initial begin
ST2 st2 = '{ 2'b01, {3'b1, 3'b0, 12'b1} };
$display("st2:%s", st2);
end
endmodule
```
Note that I have added the module "inner_submod" and its input/output ports to the first module declaration, and I have also added semicolons at the end of each inner_submod instantiation.
