Numerous examples that call the Format method are interspersed through the Remarks section of this article. Replaces one or more format items in a string with the string representation of a specified object.įormat(IFormatProvider, CompositeFormat, Object)įormat(IFormatProvider, CompositeFormat, TArg0, TArg1, TArg2)įormat(IFormatProvider, CompositeFormat, TArg0, TArg1)įormat(IFormatProvider, CompositeFormat, TArg0) Replaces the format item in a specified string with the string representation of a corresponding object in a specified array. A parameter supplies culture-specific formatting information. Replaces the format items in a string with the string representations of corresponding objects in a specified array. A parameter supplies culture-specific formatting information.įormat(IFormatProvider, String, Object) Replaces the format item or items in a specified string with the string representation of the corresponding object. Replaces the format items in a string with the string representation of two specified objects.įormat(IFormatProvider, CompositeFormat, ReadOnlySpan) ![]() Replaces the format items in a string with the string representation of two specified objects. Replaces the format items in a string with the string representation of three specified objects.įormat(IFormatProvider, String, Object, Object) An parameter supplies culture-specific formatting information. Replaces the format items in a string with the string representation of three specified objects. Overloads Format(IFormatProvider, String, Object, Object, Object) See the Remarks section for general documentation for the String.Format method. If you are new to the String.Format method, see the Get started with the String.Format method section for a quick overview. Generally, the map() function is used to map values of one collection to another, typically using a different (or even reduced) format.įor instance, you could map each character to another list of booleans, where each boolean represents if the character is uppercase or not.Converts the value of objects to strings based on the formats specified and inserts them into another string. This results in: MKVNLILFSLLVĬonvert List to String in Python with map()įinally, for a more clean and easy way to pass elements through a function - we can use map(). We've passed in the capitalize_char() function into the list comprehension, returning the capitalized version of each element we've passed in. M and f have been flipped to lowercase, which shouldn't have happened. ![]() String = "".join(capitalize_char(element) for element in base_list) For instance, let's create a function that capitalizes each element in the 'off chance' an element isn't capitalized as it should be: base_list = ĭef capitalize_char( char): return char.upper() You can substitute this with any other function, including custom ones. ![]() If you do have to convert the elements, you can simply use a list comprehension: string = "".join( str(element) for element in base_list)Įach element in the list is now passed through the str() function, which converts them to a string. Note: Python implicitly converts any data types it can, so you won't need to explicitly convert them in most cases.
