是否有用于创建变量的Python函数？

Question

我正在做一个python项目，我想创建几个变量，所有变量都包含相同的信息；然而，我无法独自解决这个问题

而不是写：

a = 1
b = 1
c = 1

等等，我想自动化这个过程。 以下是我迄今为止尝试过的一些例子：

示例1:

random.randint(0, 100) = 1

示例2:

str(random.randint(0, 100)) = 1

示例3:

class makevariable:
  random = 0

setattr(makevariable, 'random', random.randint(0, 1000)) 
getattr(makevariable, 'random') = 1

Answer 1

您可能需要一本list（可能是一本字典，dict）

import random

my_vars = [random.randint(0, 100), random.randint(0, 100), random.randint(0, 100)] # a list
print(my_vars)

# alternatively..
my_vars = [] # an empty list
for ix in range(3):
    my_vars.append(random.randint(0, 100)) # add one element at a time
print(my_vars)

# ... or more smoothly constructed using comprehension
my_vars = [random.randint(0, 100) for ix in range(3)]
print(my_vars)

# look at just the first element
print(my_vars[0]) # note the list is zero indexed

# look at just the second element
print(my_vars[1])

# how many elements?
print( len(my_vars) )

# doesn't have to be the same type
my_vars = ['fred', 3, 100/7, "Hello"]

# iterate across the list
for one_var in my_vars:
    print(one_var)
