生成随机名称列表 - Python

Question

I'm trying to create a list of names, with each one being different. Here is my code right now, but all it does it create multiple instances of the same name.

import random

first_names=('John','Andy','Joe')
last_names=('Johnson','Smith','Williams')

full_name=random.choice(first_names)+" "+random.choice(last_names)

group=full_name*3

For example, this would show up as:

John Smith
John Smith
John Smith

But I want something like:

John Williams
Andy Johnson
Joe Johnson

Answer 1

you're just duplicating your string here. Random occurs only once.

Do it in a generator comprehension instead, and join the results with space:

import random

first_names=('John','Andy','Joe')
last_names=('Johnson','Smith','Williams')

group=" ".join(random.choice(first_names)+" "+random.choice(last_names) for _ in range(3))


print(group)

outputs:

Joe Williams Joe Johnson Joe Smith

Answer 2

This is because you generated one name and then replicated it three times.

If you want three different names, then loop through your choice routine three times:

group = []
for i in range(3):
    full_name=random.choice(first_names)+" "+random.choice(last_names)
    group.append(full_name)
 #assuming he wants at least some kind of seperator between the names.
 group_string = ", ".join(group)

BTW, do you really want group to be all the names just concatenated?

Answer 3

Since the output is on one line with spaces separating each name, you can simplify the code and store every name in one list, albeit you append names in the "first name" "last name" pattern. From there you can print 6 names at the end all seperated by a space, giving you three full names. In all, the 'random.choice()' function will need to be called 6 times.

import random

first_names=('John','Andy','Joe')
last_names=('Johnson','Smith','Williams')
names = []
for i in range(3):
    names.append(random.choice(first_name)
    names.append(random.choice(last_name)

print ' '.join(names)

output

Andy Smith Andy Williams John Johnson

Answer 4

What you did is use *3 on a string which means it will copy that string three times.

To do what you want, you have to call random.choice for first name and for last name three times.

full_name1 = random.choice(first_names)+" "+random.choice(last_names)
full_name2 = random.choice(first_names)+" "+random.choice(last_names)
full_name3 = random.choice(first_names)+" "+random.choice(last_names)

group = full_name1 + " " + full_name2 + " " + full_name3

You can also do that in a for loop to not duplicate the code.

Answer 5

you need to invoke random.choice() 3 times other than invoking once and print the same fullname 3 times

import random

first_names=('John','Andy','Joe')
last_names=('Johnson','Smith','Williams')
group = list()
for x in range(3):
    fullname = random.choice(first_names)+" "+random.choice(last_names)
    group.add(fullname)
print " ".join(group)

Answer 6

... just shorter.

from random import choice
first_names=('John','Andy','Joe')
last_names=('Johnson','Smith','Williams')

name = " ".join(["%s %s" % (choice(first_names), choice(last_names)) for _ in range(3)])    

Answer 7

there is an error for this one anyway...

import random
first_name=('Hyun','Rocky','Tinisha','Kristine','Jasmin','Antony','Tracie','Christeen','Tyra','Bert')
last_name=('smith','jackson','phil','connor','O-riely','shane','josh','megalbobadio','sally','patel')
names = []
for i in range(3):
    names.append(random.choice(first_name)
    names.append(random.choice(last_name)

print ' '.join(names)

Answer 8

You could put the main part in a function with a print in it and then call the function 3 times.

def name():
    import random
    
    first_names=('John','Andy','Joe')
    last_names=('Johnson','Smith','Williams')
    
    full_name=random.choice(first_names)+" "+random.choice(last_names)
    print(full_name)
for _ in range(3):
    name()

Answer 9

pip install names

Create random names with python Then to create random names just do:

import names

for i in range(10):
    print(names.get_full_name())

Answer 10

MY MISTAKE!

You should try not to make the list too long-the string wont work-or at least for me it didnt names.append(random.choice(last_name) it showed an error my fault
