}how to verify json format is valid
I use Gson class in order to convert a
Json object into a java object.
If it works without any error, it means that it is a valid json format...
import com.google.gson.Gson;
public class JSONUtils {
Gson gson = new Gson();
public boolean isJSONValid(String jsonInString) {
try {
gson.fromJson(jsonInString, Object.class);
return true;
} catch(com.google.gson.JsonSyntaxException e) {
return false;
}
}
}JSON validate
#convert column to string
df['movie_title'] = df['movie_title'].astype(str)
#but it remove numbers in names of movies too
df['titles'] = df['movie_title'].str.extract('([a-zA-Z ]+)', expand=False).str.strip()
df['titles1'] = df['movie_title'].str.split('(', 1).str[0].str.strip()
df['titles2'] = df['movie_title'].str.replace(r'\([^)]*\)', '').str.strip()
print df
