python-字符串、列表、元祖之间的转换

1.字符串转换成列表

s = 'erfwerg'
v = list(s)
print(v)  # 输出结果：['e', 'r', 'f', 'w', 'e', 'r', 'g']

2.字符串转换成元祖

s = 'erfwerg'
v = tuple(s)
print(v)  # 输出结果：('e', 'r', 'f', 'w', 'e', 'r', 'g')

3.列表转换成功字符串

# 列表中只有字符串
li = ['qqq', 'aaa', 'www', 'eee', 'ggg']
s = ''.join(li)
print(s)    # 输出结果：qqqaaawwweeeggg

# 列表中既有数字，又有字符串
li = ['qqq', 'aaa', 555, 'eee', 'ggg', 111]
s = ''
for new_li in li:
    s = s + str(new_li)
print(s)    # 输出结果：qqqaaa555eeeggg111

4.列表转换成元祖

li = ['qqq', 'aaa', 666, 'eee', 'ggg']
v = tuple(li)
print(v)     # 输出结果：('qqq', 'aaa', 666, 'eee', 'ggg')

5.元祖转换成列表

tu = ('qqq', 'aaa', 666, 'eee', 'ggg')
v = list(tu)
print(v)     # 输出结果：['qqq', 'aaa', 666, 'eee', 'ggg']

6.元祖转换成字符串

#元祖中只有字符串
tu = ('qqq', 'aaa', 'www', 'eee', 'ggg')
v = ''.join(tu)
print(v)     # 输出结果：qqqaaawwweeeggg

#元祖中既有数字，又有字符串
tu = ('qqq', 'aaa', 1111, 'eee', 'ggg')
s=''
for new_tu in tu:
    s=s+str(new_tu)
print(s)      # 输出结果:qqqaaa1111eeeggg
