Julia join()用法及代碼示例

join() 是 julia 中的一個內置函數，用於將字符串數組連接成單個字符串。指定的分隔符用於在返回的字符串之間插入。

用法:

join([io::IO, ] strings, delim, last)

參數：

[io::IO, ] 字符串：指定的字符串。
delim:指定的分隔符。
last:如果給定了 last，則將最後一個參數插入到最後兩個字符串之間。

返回值：它返回一個新的單個字符串。

範例1：

Python


# Julia program to illustrate
# the use of String join() method
 
# Joining an array of strings into a single string.
println(join(["Geeks", "for", "Geeks"]))
println(join(["Geeks", "for", "Geeks"], "-"))
println(join(["Geeks", "for", "Geeks"], "+"))
println(join(["Geeks", "for", "Geeks"], "-", "+"))
println(join(["Geeks", "for", "Geeks", "is", "CSE", "portal"], "-", "+"))

輸出：

GeeksforGeeks
Geeks-for-Geeks
Geeks+for+Geeks
Geeks-for+Geeks
Geeks-for-Geeks-is-CSE+portal

範例2：

Python


# Julia program to illustrate
# the use of String join() method
 
# Joining an array of strings into a single string.
println(join(["1", "2", "3"]))
println(join(["1", "2", "3"], "-"))
println(join(["1", "2", "3"], "+"))
println(join(["1", "2", "3"], "-", "+"))
println(join(["1", "2", "3", "4", "5", "6"], "-", "+"))

輸出：

123
1-2-3
1+2+3
1-2+3
1-2-3-4-5+6
