如何在Python中将字符串转换为数组详解

string = 'www,jiyik,com'

# ✅ 将逗号分隔的字符串转换为数组
array = string.split(',')
print(array)  # 👉️ ['www', 'jiyik', 'com']

# ---------------------------------------------

# ✅ 将空格分隔的字符串转换为数组
string = 'www jiyik com'
array = string.split(' ')
print(array)  # 👉️ ['www', 'jiyik', 'com']

# ---------------------------------------------

# ✅ 将字符串转换为字符数组

string = 'jiyik'
array = list(string)
print(array)  # 👉️ ['j', 'i', 'y', 'i', 'k']

# ---------------------------------------------

# ✅ 将字符串转换为整数数组

string = '1,2,3'
array = list(int(char) for char in string.split(','))
print(array)  # 👉️ [1, 2, 3]

# ---------------------------------------------

# ✅ 将字符串转换为单元素数组
string = 'jiyikcom'

array = [string]
print(array) # 👉️ ['jiyikcom']

string = 'www,jiyik,com'

array = string.split(',')
print(array)  # 👉️ ['www', 'jiyik', 'com']

string = 'www jiyik com'
array = string.split()
print(array)  # 👉️ ['www', 'jiyik', 'com']

string = 'jiyik'
array = list(string)
print(array)  # 👉️ ['j', 'i', 'y', 'i', 'k']

from ast import literal_eval

my_str = '[1,2,3,4]'


my_list = literal_eval(my_str)
print(my_list)  # 👉️ [1, 2, 3, 4]
print(type(my_list))  # 👉️ <class 'list'>

string = '1,2,3'
array = list(int(digit) for digit in string.split(','))
print(array)  # 👉️ [1, 2, 3]

#方法1
arr = ['a','b']
str1 = ''.join(arr)
 
#方法2
arr = [1,2,3]
#str = ''.join(str(i) for i in arr)#此处str命名与str函数冲突！
str2 = ''.join(str(i) for i in arr)
