The code return all the phone numbers in the csv file. I want it to stop after it gets the first number. Thats what the break is there for. But it just keeps going.
It is because there two loops: one for 'row in reader', one for 'i in range'.
To completely go out of all loops, you should use two breaks and a flag.
flag = False
for row in reader:
if flag:
break
for i in range(len(list_of_column_names[0])):
if isPhoneNumber(str(row[list_of_column_names[0][i]])) == True:
flag = True
print(row[list_of_column_names[0][i]])
break
