Python——字符串的连接

# Demo: Now we have a big list with different base data bype(str,int,float)
# we need to contact them into a fianl string

src = ['abc', 123, 'defg', 49.8, '2021-01-21', '21:23:25']

# solution 1:[not recommended as it cost a lot of memory]
dest = ''

for x in src:
	dest += str(x)

print(dest)

#solution 2: [recommended]
dest = ''.join((str(x)  for x in src))
print(dest)

运行结果：

abc123defg49.82021-01-2121:23:25
abc123defg49.82021-01-2121:23:25
