1) Set to String: s = set({1,2,3,4}) # set with int values. Convert each value of set as a string, and join them to return one string with , as a delimiter. str_val = ', '.join(list(map(str, s))) output of str_val: '1, 2, 3, 4' 2) String to Set: Split th...
, one would use the already supplied string 'argument_data' to: serve as an 'identifier name' (to display, log, string split/concat, whatever) feed the eval() function in order to get a reference to the actual identifier, and therefore, a reference to the real data: print("Currently w...
输出s的值。 这将创建新的String对象,并将其与下面的文本一起打印出来。 如果新String对象的名称不同,请将这里的s替换为您自己的String对象的名称。 例如,如果您使用myNewString=str(I),那么这里的行应该类似于print“the number is”+myNewString。 写在最后 上面讲到了两个知识点, str() - 格式化函数 + ...
Pythonprovides different variable type for programmers usage. We can use int, float, string, list, set … data types in our applications. While using different type of variables we may need to convert then to different types. In this tutorial we will different type of conversion from list to...
The simplest kind of structured object we use for text processing is lists of words. When we want to output these to a display or a file, we must convert these lists into strings. To do this in Python we use the join() method, and specify the string to be used as the“glue”: ...

在上面的代码中,我们使用set()方法将字符串"123"赋值给了string_var。 3. 将StringVar转换为整数 要将StringVar转换为整数,我们可以使用内置的int()函数。下面是一个完整的代码示例: importtkinterastkdefconvert_to_int():try:value=int(string_var.get())# 在此处进行其他操作print(value+10)# 打印转换后的...
