str():将变量转化为字符串类型

a = 1

b = [1, 2, 3]

str_a = str(a)

print(a)

print(type(a))

str_b = str(b)

print(b)

print(type(b))

The str() function is meant to return representations of values which are fairly human-readable, while repr() is meant to generate representations which can be read by

the interpreter (or will force a SyntaxError if there is not equivalent syntax). For objects which don't have a particular representation for human consumption, str() will

return the same value as repr(). Many values, such as numbers or structures like lists and dictionaries, have the same representation using either function. Strings and。
