while True:

    if name == "DONE" or tanggal == "DONE":
        break
    elif name != "DONE":
        allData.append(name)
        tanggaldata.append(tanggal)
        continue

for data in allData:
    for tanggaldatas in tanggaldata :
        print(data  " lahir pada tanggal "  tanggaldatas)

When i want to print for each but there is a double print instead like : enter image description here

CodePudding user response：

You are printing doubles because you have a loop inside of a loop. You don't need the second loop

for tanggaldatas in tanggaldata :

For every person you are already getting a name and date so there will always be the same amount of both. Instead use a for loop with a counter till the length one of the arrays so you can get the element at the same index. ie.

for i in range(len(allData)):
   print(allData[i]  " lahir pada tanggal "  tanggaldata[i])
